(E)4x-10+8=-6+2x

Mim ajuda

Answer 1

(A)

9x - 8 + 4 = 16 - 5x
9x + 5x = 16 + 8 - 4
14x = 20
x = 20/14
x = 10/7

(B)
6x + 3 - 2 = 10 - 3x
6x + 3x = 10 - 3 + 2
9x = 9
x = 1

(C)
8x - 10 + 6 = 14 - 5x
8x + 5x = 14 + 10 - 6
13x = 24 - 6
13x = 18
x = 18/13

(D)
5x + 8 - 4 = 12 - 3x
5x + 3x = 12 - 8 + 4
8x = 8
x = 1

(E)
4x - 10 + 8 = - 6 + 2x
4x - 2x = -6 + 10 - 8
2x = - 4
x = -4/2
x = -2
