5(a - 7) + 7= 2(a - 5)
5a -2a= 3a
14 - 5 = 9
Am I doing it right?

5 ( a - 7 ) + 7 = 2 ( a - 5 )

5 * a - 5 * 7 + 7 = 2 * a - 2 * 5

5 a - 35 + 7 = 2 a - 10

5 a - 28 = 2 a - 10 Subtract 2 a to both sides

5 a - 28 - 2 a = 2 a - 10 - 2 a

3 a - 28 = - 10 Add 28 to both sides

3 a - 28 + 28 = - 10 + 28

3 a = 18 Divide both sides by 3

3 a / 3 = 18 / 3

a = 6
