Question

How do you solve `10x-7=-9x-26`?

Answer 1

`x=-19`

Explanation:

Put like terms on the same side of the equation. Remember what you do to one side of the equation, you to the other, and so if you add `9x` to one side you must add `9x` to the other.

Firstly, you rearrange the equation so like terms are on the same side (`x's` are on one side, and the rest is on the other side).

`10x + 9x = -26 + 7`

Simplify the equation and you get

`x=-19`
