Question

1.5x - 7 + 3x = 20
(please show step by step)​

Answer 1

x=6

Explanation:

1.5x-7+3x=20 step 1 add 1.5x to 3x

4.5x-7=20 step 2 add 7 on both sides

4.5x=27 step 3 divide 4.5 on both sides

x=6

Answer 2

x = 6

Explanation:

1.5x - 7 + 3x = 20

Combine 1.5x and 3x to get 4.5x.

4.5x - 7 = 20

Add 7 to both sides.

4.5x = 20 + 7

Add 20 and 7 to get 27.

4.5x = 27

Divide both sides by 4.5.

x =
`(27)/(4.5)`

Expand
`(27)/(4.5)` by multiplying both numerator and the denominator by 10.

x =
`(270)/(45)`

Divide 270 by 45 to get 6.

x = 6
