Question 175231: Please help me expalin the answer to this problem -2(1+5a)=-4+6(a+3)
Answer by EMStelley(208)   (Show Source):
You can put this solution on YOUR website! The first step is to distribute through on both sides. So
-2(1+5a) = -4+6(a+3) becomes
-2(1) + -2(5a) = -4 + 6a + 6(3)
-2 - 10a = -4 + 6a + 18
-2 - 10a = 14 + 6a
Next, we need to combine the "a" terms and combine the constants. So, add 10a to both sides, and subtract 14 from both sides.
-16 = 16a
Lastly, dividing by 16 on both sides yields a = -1.
