Question

H) 4(x+5) = 2 (x+1)

I) 8(x-6) = ½

J 6(x+10) = 2x+5

Ajuda por favor

Answer 1

h) 4(x + 5) = 2(x + 1)

4x + 20 = 2x + 2

4x - 2x = 2 - 20

2x = -18

x = -18 / 2

x = - 9

i) 8(x - 6) = 1/2

8x - 48 = 1/2

16x/2 - 96/2 = 1

16x - 96 = 1

16x = 1 + 96

16x = 97

x = 97/16

j) 6(x + 10) = 2x + 5

6x + 60 = 2x + 5

6x - 2x = 5 - 60

4x = - 55

x = - 55/4
