x=__
2.Solve for x: −4(1.75 + x) = 18
x=__
3.Solve for x: 6x - 9 = 42
x=__

Answer 1

1. x = 7596

2. x = -6.25

3. x = 8.5

hope this helps:)

Answer 2

`1)(x)/(12) +15=648\\\\(x)/(12)=648-15\\\\(x)/(12)=633\\\\x=633*12\\\\x=7596`

`2) -4(1.75+x)=18\\\\-7-4x=18\\\\-4x=18+7\\\\-4x=25\\\\x=-(25)/(4)`

`3)6x-9=42\\\\6x=42+9\\\\6x=51\\\\x=(51)/(6)`
