Question

-11 - 5a = 6(5a+4) ?? Totally having a brain fart

Answer 1

Answer: a=-1

Step-by-step explanation:

-11-5a=6(5a+4)

-11-5a=30a+24

-11-5a-30a=24  

-5a-30a=24+11

-35a=35            

a=-1                 

Answer 2

-11-5a=6(5a+4) .... Distribute the 6 to 5a and 4
-11-5a=30a+24 .... Subtract 30a from both sides
-11-5a-30a=24  .... Add 11 from both sides
-5a-30a=24+11 .... Add like terms
-35a=35            .... Divide -35a from both sides
a=-1                  .... Final answer
