f)17x-7x=x+18

g)x+x-4=17-2x+1


me ajudemm,com os cálculos pfv

Answer 1

Explicação passo-a-passo:

c) 2x+3=x+4

2x-x=4-3

x = 1

d) 5x + 7 = 4x+ 10

5x - 4x = 10-7

x = 3

e) 5x - 3 + x = 2x + 9

6x - 2x = 9+ 3

4x = 12

x = 3

f) 17x - 7x = x + 18

17x - 7x - x = 18

9x = 18

x= 2

g) x + x - 4 = 17 - 2x + 1

2x + 2x = 17 + 1 + 4

4x = 22

x = 5.5
