−3(2a−14)−3a=24
what is a

Answer 1

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

`- 3(2a - 14) - 3a = 24`

`- 6a + 42 - 3a = 24`

`- 9a + 42 = 24`

Subtract sides 42

`- 9a + 42 - 42 = 24 - 42`

`- 9a = - 18`

Divide sides by - 9

`( - 9a)/( - 9) = ( - 18)/( - 9) \\`

`a = 2`

CHECK :

`- 3(2(2) - 14) - 3(2) = 24`

`- 3(4 - 14) - 6 = 24`

`- 3( - 10) - 6 = 24`

`30 - 6 = 24`

`24 = 24`

Thus the solution is correct.....
