Question

9 x+3(2x-8)=4(2x+13)+72

Answer 1

9x +3 (2x-8)=4 (2x+13) +72
9x + 6x - 24 = 8x +52 + 72
9x + 6x - 24 = 8x +52 + 72
15x - 24 = 8x  + 124
15x - 8x = 124 + 24
7x = 148
x = 148 / 7

Resposta : x = 148/7

Answer 2

Oi, Eduardo.

9 x + 3 ( 2 x - 8 ) = 4 ( 2 x + 13 ) + 72

9 x + 6 x - 24 = 8 x + 52 + 72

15 x - 8 x = 148

7 x = 148

X = 148 / 7

X = 21,14 aproximadamente.
