Question

Solve the linear equation and verify your answer
9(x+21)=54

Answer 1

Answer:

The Correct Answer is -15

Step-by-step explanation:

9(x+ 21) = 54

(x + 21) = 6

x = 6 -21

x = -15

Verification:

9 ( -15 + 21 ) = 54

9 ( 6 )  = 54

54 = 54

LHS is equal to RHS therefore the value of x is correct

Answer 2

Step-by-step explanation:

9(x+21)=54

(x+21)=6

x=6-21

x=-15

Verification

9(-15+21)=54

9(6)=54

54=54

LHS =RHS
