x= -5

here's how you solve it:
2x - 1 = 3x + 4
subtract 2x from both sides to get
-1 = x + 4
the subtract -4 from both sides and your result will be
-5 = x
to check if it's right plug the -5 in the x:
2(-5) - 1 = 3 (-5) + 4
-10 - 1 = -15 + 4
-11 = -11

2x-1=3x+4
Subtract 3x from both side:
-x-1=4
Add 1 from both sides:
-x=5
Divide -1 from both sides:
x=-5
Check:
2(-5)-1=3(-5)+4
-10-1=-15+4
-11=-11

2x-1+1=3x+4+1
2x=3x+5
2x-3x=3x-3x+5
-x=5
x=-5(divide both sides by -1)
