Answer:

Explanation:
Simplify the expression:
2x + 35 + 8x - 49 = 90
Subtract:
2x + 35 + 8x - 49 = 90
2x - 14 + 8x = 90
Combine terms:
2x-14+8x = 90
10x - 14 = 90
Add 14:
10x - 14 = 90
10x - 14 + 14 = 90 + 14
Simplify:
10x - 14 + 14 = 90 + 14
Add:
10x - 14 + 14 = 90 + 14
10x = 90 + 4
Add:
10x = 90 + 14
10x = 104
10x = 104
Divide:
10x = 104
10x / 10 = 104/10
Simplify:
10x / 10 = 104/10
Cancel terms for both numerator and denominator:
10x / 10 = 104 / 10
x = 104 / 10
Divide
x = 104/10
x = 52 / 5
x = 52 / 5
x = 10.4
Answer:

Thus the answer to your problem is,
