Question

part A: is x=6 a solution of the equation 8x+18=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 no x=9?

Answer 1

`8x = 56 - 18`

`8x = 38`

`x = 4.75`

`4.75 = no \: 6`
part b

the right part will become 90

`8x(9) + 18 = 90`

`72 + 18 = 90`

`90 = 90`
