Someone the equation. b/-4 = -2

a. 8
b. -8
c. 1/2
d. -1/2

When solving algebraic equations, first decide what variable need to solved. In this case, the b variable. When solving for a variable, get the variable on one side and everything else on the opposite side of the variable you're solving for.

We have the equation 

What can we do to get the b variable by itself? Well, we can multiply the left-hand side of the equation by -4. But any thing we do on one side, we must do on the opposite side.



So, b is equal to 8.

Opposite angles in a cyclic quadrilateral add up to 180°
