Question

01- Determine os valores de X: a) X + 1 = 10 b) 2X – 4 = 3 – 6X c) 2X + 10 = 20 d) 2(X + 1)= X + 10

Answer 1

Resposta:

a) x=9

b)x=0,875

c)x=5

d)x=8

Answer 2

Resposta:

a)9 b)7/8 c)5 d)8

Explicação passo-a-passo:

a)10 - 1 = x / x = 9

b)2x + 6x = 3 + 4 / 8x = 7 / x = 7/8

c)20 - 10 = 2x / 10 = 2x / x = 10/2 / x = 5

d)2x + 2 = x + 10 / 2x - x = 10 - 2 / x = 8
