Question

2) Resolva as equações a seguir:
a)18x - 43 = 65
b) 23x - 16 = 14 - 17x
c) 10y - 1 +5y = 6y +6 +20
d) 2x +4x=12 +52
e) 5x+10= -5x + 120
f) 4x -2= x+92​

Answer 1

Resposta:

a) x=6

b) x= 3/4

c) x= 3

d) x= 32/3

e) x=11

f) x=94/3

Explicação passo-a-passo:

a)18x - 43 = 65

18x= 65 + 43

18x = 108

x= 108/18

x=6

b) 23x - 16 = 14 - 17x

23x+17x=14+16

40x = 30

x = 30/40 simplifique por 10

x = 3/4

c) 10y - 1 +5y = 6y +6 +20

10y+5y-6y=1+6+20

9y=27

y=27/9

y=3

d) 2x +4x=12 +52

6x=64

x=64/6 simplifique por 2

x= 32/3

e) 5x+10= -5x + 120

5x+5x=120-10

10x=110

x=110/10

x=11

f) 4x -2= x+92​

4x-x=92+2

3x=94

x=94/3
