Question

(3x+5)+(2x+1)=5(x-1)+9

Answer 1

I'm not going to do all your homework for you :P

Solution is the same here as before, combine x terms on one side, factor out and divide off the rest.

Answer 2

5x + 6 = 5x + 4

No Solution

Answer 3

3x + 5 + 2x + 1 = 5x -5 + 9
3x + 2x + 5 + 1 = 5x - 5 + 9
5x + 5 + 1 = 5x - 5 + 9
5x + 6 = 5x - 5 + 9
6 = 5 + 9
6 = 14

Therefore this equation makes no sense, and has no solution.

Answer 4

I had a type, 6 = -5 + 9 in the second to last line and
6 = 4 in the last line
