Question

4(x + 5)=2x + 34
10(x + 2)=8x + 22
5(x + 4)=38x + 10) -8
x + 192 (x + 6)

Answer 1

Respuesta:

Facil

Explicación paso a paso:

1) 4(x + 5)=2x + 34

4x + 20 = 2x + 34

4x - 2x = 34 - 20

2x = 14

x = 14/2

x = 7

2) 10(x + 2)=8x + 22

10x + 20 = 8x + 22

2x = 2

x= 1

3) 5(x + 4)=38x + 10 -8

5x + 20 = 38x + 2

20 - 2 = 38x - 5x

18 = 33x

18/33 = x
