Question

43= -7x - 4 (-5x+12)

Answer 1

7x

Explanation:

First distribute the -4 with the (-5x+12) which should be 20x-48 and then simplify and it should be 43=13x-48. Then add 48 to both sides which should be 91=13x. Lastly divide 13 on both sides and that should be 7x.

Answer 2

x= 91/27

Explanation:

remove parenthesis, collect like terms, move the terms, calculate, and ive by both sides
