Question

A) 4x+10-5=25-x
B) 22-4+3x=40+x-6
C) 25+4x-5=65-x-10
D) -12+2x+6=15-x-3
​

Answer 1

A) 4x + 10 - 5 = 25 - x

4x + 5 = 25 - x

4x + x = 25 - 5

5x = 20

x = 20/5

x = 4

B) 22 - 4 + 3x = 40 + x - 6

18 + 3x = 34 + x

3x - x = 34 - 18

2x = 16

x = 16/2

x = 8

C) 25 + 4x - 5 = 65 - x - 10

20 + 4x = 55 - x

4x + x = 55 - 20

5x = 35

x = 35/5

x = 7

D) - 12 + 2x + 6 = 15 - x - 3

- 6 + 2x = 12 - x

2x + x = 12 + 6

3x = 18

x = 18/3

x = 6
