On this page, you will find Math word and story problems worksheets with single- and multi-step solutions on a variety of math topics including addition, multiplication, subtraction, division and other math topics. It is usually a good idea to ensure students already have a strategy or two in place to complete the math operations involved in a particular question. There are a number of strategies used in solving math word problems; if you don't have a favorite, try the Math-Drills.
Solving two-step equations Video transcript We have the equation negative 16 is equal to x over 4, plus 2. And we need to solve for x. So we really just need to isolate the x variable on one side of this equation, and the best way to do that is first to isolate it-- isolate this whole x over 4 term from all of the other terms.
And the best way to get rid of that 2 is to subtract it. But if we want to subtract it from the right-hand side, we also have to subtract it from the left-hand side, because this is an equation. If this is equal to that, anything we do to that, we also have to do to this.
So you subtract 2 from the right, subtract 2 from the left, and we get, on the left-hand side, negative 16 minus 2 is negative And then that is equal to x over 4.

And so we have negative 18 is equal to x over 4. And our whole goal here is to isolate the x, to solve for the x. So we can multiply that by 4, but once again, this is an equation. Anything you do to the right-hand side, you have to do to the left-hand side, and vice versa.
So if we multiply the right-hand side by 4, we also have to multiply the left-hand side by 4.
So we get 4 times negative 18 is equal to x over 4, times 4. The x over 4 times 4, that cancels out. And on the other side, 4 times negative So 18 times 4.
If we were to multiply 18 times 4, 4 times 8 is So x is equal to negative And if we want to check it, we can just substitute it back into that original equation.
So this right-hand side simplifies to negative 72 divided by 4. We already know that that is negative So this is equal to negative 18 plus 2. This is what the equation becomes.
So it all comes out true. This right-hand side, when x is equal to negative 72, does indeed equal negative Solving equations.

Opposites. When solving equations in algebra, doing the opposite operation is usually required. One way to keep your equation balanced is to move things around by doing the opposite because you have to undo operations that have been done to the variable.
The opposite of an operation is one way to move things around in an equation. You can step by step solve your algebra problems online - equations, inequalities, radicals, plot graphs, solve polynomial problems. If your math homework includes equations, inequalities, functions, polynomials, matrices this is the right trial account.
