Question

What is x? 3x - 4 + 1 = - 2x - 5 + 5x

Answer 1

3x-4+1=- 2x-5+5x
3x-5x+2x=4-1+5
- 2x+2x=8
0x=8
x=8/0
x=infinity

Answer 2

3x - 4 + 1 = -2x - 5 + 5x

First, simplify 3x - 4 + 1 to 3x - 3. / Your problem should look like: 3x - 3 = -3x - 5 + 5x
Second, simplify -2x - 5 + 5x to 3x - 5. / Your problem should look like: 3x - 3 = 3x - 5
Third, cancel 3x on both sides. / Your problem should look like: -3 = -5
Fourth, since -3 = -5 is false, there is no solution.

Answer: No solution
