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


Sagot :

Answer:

x = 6

Step-by-step 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 = [tex]\frac{27}{4.5}[/tex]

Expand [tex]\frac{27}{4.5}[/tex] by multiplying both numerator and the denominator by 10.

x = [tex]\frac{270}{45}[/tex]

Divide 270 by 45 to get 6.

x = 6

Hope it helps and have a great day! =D
