18 = -3y

3 answers

To solve for y, you need to isolate the variable on one side of the equation.

Given the equation 18 = -3y, divide both sides of the equation by -3:

18 / -3 = (-3y) / -3

This simplifies to:

-6 = y

So, y equals -6.
9w = -36
To solve for w, you need to isolate the variable on one side of the equation.

Given the equation 9w = -36, divide both sides of the equation by 9:

(9w) / 9 = (-36) / 9

This simplifies to:

w = -4

So, w equals -4.
