Question

Resolva as equacoes a)5(x+1)=2(2+3+1) b) 6x+1=2×-3 c)9×-7=5×+13 d)6×=2×+180

Answer 1

Resposta:

a) x = 8/5

b) x = -1

c) x = 5

d) x = 45

Explicação passo a passo:

a)5(x+1)=2(2+3+1)

5x + 5 = 4 + 6 + 2

5x = 12 - 5

5x = 8

x = 8/5

b) 6x+1=2×-3

6x - 2x = -3 - 1

4x = -4

x = -1

c)9×-7=5×+13

9x - 5x = 13 + 7

4x = 20

x = 20/4

x = 5

d)6×=2×+180

6x - 2x = 180

4x = 180

x = 180/4

x = 45
