Question

1) Resolva as equações a seguir:
a)18x - 43 = 65
b) 23x - 16 = 14 - 17x
c) 3 + x = 0
d) 23x + 2 = 2
e) 12 – 7 + 4x = 25
f) 5x – 3x = 30
g) 4x + 10 = 45 – 3x

Answer 1

Resposta:

A = 6

B = 5

c = 3

d = 5,75

e = 11

f = 15

g = 5

Answer 2

Resposta:

a)18x-43=65

18x=65-43

18x=22

x=22/18

x=1,2

b)23x-16=14-17x

23x+17x=14+16

40x=30

x=40/30

x=1,3

c)3+x=0

x=3

d)23x+2=2

23x=2-2

x=23

e)12-7+4x=25

4x=25-12+7

4x=20

x=5

f)5x-3x=30

2x=30

x=30/2

x=15

g)4x+10=45-3x

4x+3x=45-10

7x=35

x=35/7

x=5

Espero ter ajudado:)
