Question

4(5a-8)+2a is equivalent to 12a-6

Answer 1

4(5a-8)+2a

20a-32 +2a

22a-32

if they are equivalent then they are equal

22a-32=12a-6  and we can solve for a  subtract 12 a from each side

10 a -32=-6    add 32 to each side

10 a =26   divide by 10

a = 2.6

Answer 2

32 or 43 just div it by 10 or 5
