Question

Resolva:
a) 5x-5=10
b) x+7=10
c) x-3=6
d) 6x=2x+16
e) 2x-5=+1
f) 4x=4-8+2x

Answer 1

Resposta:

Explicação passo-a-passo:

a) 5x-5=10

5 x = 10 + 5

5 x = 15

x = 15 / 5

x = 3

b) x+7=10

x = 10 - 7

x = 3

c) x-3=6

x = 6 + 3

x = 9

d) 6x=2x+16

6x - 2x = 16

4 x = 16

x = 16 / 4

x = 4

e) 2x-5=+1

2 x = 1 + 5

2 x = 6

x = 6 / 2

x = 3

f) 4x=4-8+2x

4 x - 2x = 4 - 8

2 x = - 4

  x = - 4 / 2

 x = - 2
