Question

Calcule

1- 2x-8=3x-10

2- 18x-43=65

3- 23x-16=14-17x

4- 3(x-4)=0

Answer 1

Resposta:

1-

2x-8 = 3x-10

2x - 3x = -10 +8

-1x = -2. .(-1)

x = 2 ✔️

2-

18x-43 = 65

18x = 65 +43

18x = 108

x = 108 / 18

x = 6 ✔️

3-

23x - 16 = 14 - 17x

23x + 17x = 14 + 16

40x = 30

x = 30 /40 (simplif ÷10)

x = 3/4 ✔️

4-

3(x-4)=0

3x - 12 = 0

3x = 12

x = 12/3

x = 4 ✔️
