Question

Calcule as equacãoes:

A)4X-10=-2X

B)5x-5=10

Answer 1

A) 4X - 10 = -2X
    4X + 2X =10
    6X = 10
    X = 10/6
    X = 1,67

B) 5X - 5 = 10
    5X = 10 + 5
    5X = 15
    X = 15/5
    X = 3

Answer 2

a) 4x-10= -2x
4x+2x = +10
6x = +10
x = +10/6(simplificando por 2)
x = 5/3

b) 5x -5 = 10
5x = 10+5
5x = 15
x = 15/5
x = 3
