Question 39224: i can't seem to find the answer to these problems: Can you help?
3a + (2a-5)=13-2(a+2) (i need to find what a is = to)
2(b+1)-3b=3(3+2b) (i need to find what b is = to)
Answer by Nate(3500) (Show Source): You can put this solution on YOUR website!
3a + (2a-5) = 13 - 2(a+2)
3a + 2a - 5 = 13 - 2a - 4
5a - 5 = 9 - 2a
7a = 14
a = 2
.......................................
2(b+1)-3b=3(3+2b)
2b + 2 - 3b = 9 + 6b
-b + 2 = 9 + 6b
-7 = 7b
-1 = b
