Answer:

First result: X = 248/3 or 82.67 Second result: X = 260/3 or 86.57

Explanation:

1st one: 7x + 8(x + 1/4) = 3(6x - 90 - 8)

7x + 8x + 2 = 18x - 270 - 24

15x + 2 - 2 = 18x - 246 - 2

15x - 18x = 18x - 18x -248

-3x = 248 --> -3x/3 = 248/3

X = 248/3 or X = 82.67

2nd one: 7x + 8(x+1/4) = 3(6x - 90) - 8

7x + 8x + 2 = 18x - 270 - 8

15x + 2 - 2 = 18x - 262 - 2

15x - 18x = 18x -18x - 260

-3x = 260 --> -3x/3 = 260/3

X = 260/3 or X = 86.67

Sorry if none of these are the answer!
