Answer 18

first work the parenthesis : multiply 2 wid the contents of parenthesis

2(2x - 4) + x = 7

2(2x) - 2(4) + x = 7

4x - 8 + x = 7

"4x" and "x" are like terms

Answer 24

2(2x - 4) + x = 7

2(2x) - 2(4) + x = 7

4x - 8 + x = 7

4x + x - 8 = 7

5x - 8 = 7

Answer 25

see if u can do the rest :)

Answer 39

thank you

Answer 40

np.. u wlc :)

Answer 41

could you show work

Answer 42

all together

Answer 43

2(2x - 4) + x = 7

2(2x) - 2(4) + x = 7

4x - 8 + x = 7

4x + x - 8 = 7

5x - 8 = 7

5x = 15

x = 3

Answer 44

thank you

Answer 45

u wlc :)
