C)4(×+10)=2(×+22) D)7(×+4)=5(×+6)+6 E)5(×+4)=3(×+10)-8​

Answer 1

Explicación paso a paso:

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

10x+20 = 8x+22

10x-8x = 22-20

2x = 2....x = 1

B. x+19 = 2(x+6)

x+19 = 2x+12

x-2x = 12-19

-x = - 7....x = 7

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

4x+40 = 2x+44

4x-2x = 44-40

2x = 4....x = 2

D. 7(x+4) = 5(x+6)+6

7x+28 = 5x+30+6

7x+28 = 5x+36

7x-5x = 36-28

2x = 8....x = 4

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

5x+20 = 3x+30 - 8

5x+20 = 3x+22

5x-3x = 22-20

2x = 2....x = 1
