Question

como resolver a conta 5(7X-2)-X=15+2(X-5)

Answer 1

5(7X-2)-X=15+2(X-5)
Faça a distributiva
5*7x +5*(-2) - x = 15 +2*x + 2*(-5)
35x -10 -x = 15 + 2x - 10
35x -2x -x= -10  +10 +15
35x -3x = 15
32x = 15
x = 15/32

Abraços ;)

Answer 2

35x-10-x = 15+2x-10
35x-x-2x = 15+10-10
32x = 15
x = 15/32
x = 0,4687
