Question

(12a-7)-(5a+6) =3-(8-2a). answers​

Answer 1

Answer:

Hence, answer is 8 / 5.

Step-by-step explanation:

( 12 a - 7) - (5 a + 6 ) = 3 - ( 8 - 2 a )

= 12 a - 7 - 5 a + 6 = 3 - 8 - 2 a

= 12 a - 5 - 7 - 6 = - 5 - 2 a

= 7 a - 13 = - 5 - 2 a

= 7 a - 2 a = - 5 + - 13

= 5 a = - 5 + 13

= 5 a = 8

= a = 8/5

a = 8 / 5

Answer 2

Answer:

Step-by-step explanation:

(12a-7)-(5a+6) =3-(8-2a)

12a-7-5a-6=3-8+2a

7a-2a=-5+13=8

5a=8

a=8/5
