Question

A) x/7 -1/5 =2 c) 5x - 8 =-3 e) 2x/11= 6 /33 g)5x /4 + 3 =-7 i) 5x - 8 = 5/4

Answer 1

Explicação passo-a-passo:

a) x/7 -1/5 =2

5x - 7 = 70

5x = 77

x = 77/5

c) 5x - 8 =-3

5x = 5

x = 1

e) 2x/11= 6 /33

6x/33 = 6/33

x = 1

g)5x /4 + 3 =-7

5x/4 = -10

5x = -40

x = -8

i) 5x - 8 = 5/4

5x = 32/4 + 5/4

x = 37/20
