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:

$x = -3$
