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}`
`(3a)/(3)=\text{ }\frac{\text{-30}}{3}`
`\text{ a = -10}`

At -9 x b = 45,

`-9\text{ x b = 45}`
`-9b\text{ = 45}`
`(-9b)/(-9)=(45)/(-9)`
`b=\text{ -5}`

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