Question

Solve the equation. Write a justification for each step. HELP PLEASE!!

−3(−x−2)=5x−9

Answer 1

x =
`(15)/(2)`

-3( - x - 2 ) 5x - 9 ( distribute parenthesis by multiply terms by - 3 )

3x+ 6 = 5x - 9 ( subtract 5x from both sides )

3x - 5x + 6 = - 9

- 2x + 6 = - 9 ( subtract 6 from both sides )

- 2x = - 15 ( divide both sides by - 2 )

x =
`(- 15)/(- 2)` =
`(15)/(2)`

Answer 2

x=15/2 distubute the -3
