Question

4(x + 10 ) = 2 ( x +22)
6(x+5)= 7x + 25
10 ( x + 2) = 8 x + 22
5 (x+4)= 3 (+ 10 ) -8
X+19= 2 (x+6)
me pueden ayudar ​

Answer 1

Explicación paso a paso:

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

4x + 40 = 2x + 44

4x -2x = 44 - 40

2x = 4

x = 4/2

x = 2

6(x+5)= 7x + 25

6x + 30 = 7x + 25

6x - 7x = 15 - 30

-x = -15

x = 15

10 ( x + 2) = 8 x + 22

10x + 20 = 8x + 22

10x - 8x = 22 - 20

2x = 2

x = 2/2

x = 1

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

5x + 20 = 30 - 8

5x = 30 -20 -8

5x = 2

x = 2/5

X+19= 2 (x+6)

x + 19 = 2x + 12

x - 2x = 12 - 19

-x = -7

x = 7
