Question

-12 + 8a = -a + 6(2a - 2)

Answer 1

41/6

Explanation:

-12+81=-1+6(2a-2)

first distribute:

-12+81=-1+12a-12

combine like terms:

-12+81= -1+12a-12

69=-13+12a

add -13 with 69:

82=12a

divide 82 and 12:

82/12= 41/6

Answer 2

a = 0

Explanation:

given

-12 + 8a =-a + 6(2a -2)

Distribute the righ side

-12 + 8a = -a +6x2a -6x2

-12 + 8a = -a +12a - 12

-12 + 8a = 11a -12

Collect like terms

-12 + 12 = 11a - 8a

0 = 3a

Divide both sides by 3

0/3 = 3a/3

0 = a

a = 0
