-6(a + 5) + 5a = 12 + 6a solve for a

a = - 6

Step-by-step explanation:

Given

- 6(a + 5) + 5a = 12 + 6a ← distribute and simplify left side

- 6a - 30 + 5a = 12 + 6a

- a - 30 = 12 + 6a ( subtract 6a from both sides )

- 7a - 30 = 12 ( add 30 to both sides )

- 7a = 42 ( divide both sides by - 7 )

a = - 6
