Answer
Distribute
3a + 4 = 5 ( a - 2 )
3a + 4 = 5a - 10
Subtract 4 from both sides of the equation
3a + 4 = 5a - 10
3a + 4 - 4 = 5a - 10 - 4
simplify ;
Subtract the number again
3a = 5a - 14
Subtract 5a from both sides of the equation
3a = 5a - 14
3a - 5a = 5a - 14 - 5a
simplify ;
combine like terms again
- 2a = - 14
solution
a = 7
