Question

Resolva as operações: 5(x+1) +6 (x+2)=9 (x+3)

Answer 1

5x+5+6x+12=9x+27
11x+17=9x+27
2x=10
x=5

Answer 2

Resolva as operações:
5(x+1) +6 (x+2)=9 (x+3)5x + 5   6x + 12 = 9x + 27
5x + 6x + 5 + 12 = 9x + 27
11x + 17 = 9x + 27
11x + 17- 9x = + 27
11x - 9x = + 27 - 17
2x =  10
x = 10/2
x = 5
