Question

2+7(x + 3) = 15 whats the answer
i need help

Answer 1

x = -
`(8)/(7)`

Explanation:

given

2 + 7(x + 3) = 15 ← distribute parenthesis on left side by 7

2 + 7x + 21 = 15 ← collect like terms on left side

7x + 23 = 15 ( subtract 23 from both sides )

7x + 23 - 23 = 15 - 23 ( simplify both sides )

7x = - 8 (isolate x by dividing both sides by 7 )

`(7)/(7)` x =
`(-8)/(7)` , that is

x = -
`(8)/(7)`
