Question

-8(a - 4) + 3a = 2(4a + 9) + 1

Answer 1

Answer: a=1

Step-by-step explanation:

-8(a-4)+3a=2(4a+9)+1          given

-8a+32+3a=8a+18+1            distribute

+8a             +8a

32+3a=16a+18+1                  subtraction property of equality

    -3a  -3a

32=13a+18+1                         addition property of equality

32=13a+19                             add like terms

-19        -19

13=13a                                    addition property of equality

÷13 ÷13

1=a                                          multiplication property of equality

a=1 is the answer. Hope this helps!
