Question

A)8 (4x+2)=118 B) 11x-8x-13=19-x-16 C)5 (x-3)+12=42+35​

Answer 1

Vamos lá...

a)

8(4x + 2) = 118

32x + 16 = 118

32x = 118 - 16

32x = 102

x = 102/32 ÷ 2

x = 51/16

b)

11x - 8x - 13 = 19 - x - 16

3x - 13 = 3 - x

3x + x = 3 + 13

4x = 16

x = 16/4

x = 4

c)

5(x - 3) + 12 = 42 + 35

5x - 15 + 12 = 42 + 35

5x  - 3 = 77

5x = 77 + 3

5x = 80

x = 80/5

x = 16

Espero ter ajudado.
