Question

Solve for the indicated variable using the given value of the other variable.

Solve for `x` when `y=0` using the equation `y=-3x+12`

Answer 1

Answer: x=4

Explanation:

When you substitute 0 for y you will set up your equation like this:

0=-3x+12

You will then subtract 12 from 0 to isolate x:

-12=-3x

You can then divide both sides by -3 and x will equal 4.
