Answer:
x=9
Step-by-step explanation:
5( x + 7) - 3 ( x - 4) = 7x + 2
Distribute
5x+35 - 3x +12 = 7x +2
2x +47 = 7x+2
Subtract 2x from each side
2x+47-2x =7x -2x+2
47 = 5x+2
Subtract 2 from each side
47-2= 5x+2-2
45= 5x
Divide by 5
45/5 =5x/5
9 =x
She added the numerators
instead of multiplying them
you should also simplify the final answer
the correct answer would be -3 1/8 or -25/8 as an improper fraction.

2 + 4x = 5 - 3x -3,
2 + 4x = 5 -3 - 3x
