Question

como resolvo x+5/3=x-2/10

Answer 1

(x + 5) / 3 = (x - 2) / 10                   mmc = 30

10 * (x + 5) = 3 * (x - 2)
10x + 50 = 3x - 6
10x - 3x = -6 - 50
7x = -56
x = -56/7
x = - 8..........

Answer 2

x=5/3=x-2/10
Faço regra de três
10(x+5)= 3(x-2)
10x+50= 3x-6
10x-3x= -6-50
7x= -56
x= -56/7
x= -8
Resp.: x=-8
