Question

2x - 1 = 3x + 2
3 6
A) -4
B) 2
C) 4
D) 1/4

Answer 1

For this case we must find the solution of the following equation:

`2x-1 = 3x + 2`

If we subtract 3x from both sides of the equation we have:

`2x-3x-1 = 2`

Different signs are subtracted and the major sign is placed

`-x-1 = 2`

We add 1 to both sides of the equation:

`-x=2+1\\-x=3`

We multiply by -1 on both sides of the equation:

`x = -3`

So, the solution is
`x = -3`

Answer:

`x = -3`
