Question

A)3x+18=x-58
B)6x-4x+10=30
C)3x+60=20-x
D)8x+24=96
E)2x+14=24
F)x+x+8+2x=60

Answer 1

Oi...

a) 3x + 18 = x - 58

3x - x = - 58 - 18

2x = - 76

x = - 76/2

x = - 38

b) 6x - 4x + 10 = 30

2x = 30 - 10

2x = 20

x = 20/2

x = 10

c) 3x + 60 = 20 - x

3x + x = 20 - 60

4x = - 40

x = - 40/4

x = - 10

d) 8x + 24 = 96

8x = 96 - 24

8x = 72

x = 72/8

x = 9

e) 2x + 14 = 24

2x = 24 -14

2x = 10

x = 10/2

x = 5

f) x + x + 8 + 2x = 60

4x = 60 - 8

4x = 52

x = 52/4

x = 13

Espero ter ajudado

Bons estudos.
