Question

Pfvr me ajudemm!!

Resolva as equações abaixo:

a- 5x-15=105
b- 6x-24=3x+18
c- 4x+1=17
d- 3x+15=2x-24
e- 12x-36=64+2x
f- 9x-24=57
g- 7x-49=56

Answer 1

a) 5x= +15 +105
5x= 120
x= 120
-
5
x=24


b)6x +3x = 24 + 18
9x = 42
x = 42 ÷ 9
x=4.6

c) 4x= -1 +17
x= 20

d)3x - 2x = -15 -24
x= -39


e)12x -2x= 36 +64
10x= 100
x=10

f)9x= 24 +57
9x= 81
x= 81÷9
x=9

g)7x = 49 + 56
7x = 105
x = 105 ÷ 7
x= 15
