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

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:

$x = -3$

I need help to do this question?

Answer:

you multiply 2 by everything in the first parenthesis and get 2x+10

then you multiply -3 by everything in the second parenthesis and get -3x-18

so you have 2x+10-3x-18

combine like terms and you get -1x-8 or -x-8

Hope This Helps! Have A Nice Day!!
