Are you trying to find a

jhannybean · Answer

First apply the distributive property.

anonymous · Answer

Haha Nevermind XD

jhannybean · Answer

6*a +6*3 = 21 -3 -1*1 -1 *-2a

anonymous · Answer

i do that but the thing i get stuck on is putting it all togethter

jhannybean · Answer

Oh okay. so when we simplify this we get 

6a +18 = 21 -3-1+2a  right?

We'll work through it step by step.

instead of 2a wouldnt it be -6a

jhannybean · Answer

Let's see. 

6a +18 = 21 -3-1+2a                  simplify the right side 

6a + 18 = 21-4 +2a                     simplify again

6a + 18 = 17 + 2a                        bring all the a's to one side of the equation 

6a -2a +18 = 17                           simplify left side 

4a +18 = 17                                  bring all the numbers to the other side of the equation 

4a = 17 - 18                                  simplify

4a = -1                        isolate a on one side by dividing both sides of the equation by 4

4a/4 = -1/4                                 Simplify

a = -1/4
