Question

Find the value of each variable.a × 3= -30 -9 × b= 45

Answer 1

Given the expression:

a x 3 = -30

-9 x b = 45

Let's determine the value of each variable.

At a x 3 = -30,

$\text{ a x 3 = -30}$$3a\text{ = -30}$$\frac{3a}{3}=\text{ }\frac{\text{-30}}{3}$$\text{ a = -10}$

At -9 x b = 45,

$-9\text{ x b = 45}$$-9b\text{ = 45}$$\frac{-9b}{-9}=\frac{45}{-9}$$b=\text{ -5}$

Therefore, a = -10 and b = -5.
