Question

6. Part A: Is x=6 a solution of the equation

8x + 8 = 56? Explain.
Part B: Suppose the solution x=6 increases
to x=9, and the left side of the equation
stays the same. How would the right side
need to change if the solution is now x=9?

Answer 2

x=6 is a solution

the right side should be 80

Explanation:

`8x + 8 = 56`

To check whether x=6 is a solution , plug in 6 for x

`8(6) + 8 = 56`

`48+8= 56`

56=56 both sides are equal

So x=6 is a solution

Suppose the solution x=6 increases to x=9, and the left side of the equation

stays the same.

Lets take left hand side

`8x+8`

Replace x with 9

`8(9)+8`

`72+8=80`

So the right side should be 80
