Rewrite the equation. 3x + 5 = 2x
Isolate the variable, x. 3x - 2x + 5 - 5 = 2x - 2x - 5
Write the new equation. x = -5

3x+5=2x
Group the variables by moving 2x to the other side of the equal sign. When you move a number to the other side of an equal sign you have to change it's sign( + or - )
3x - 2x+5=0
do the same thing for the 5.
3x-2x= -5
now subtract....
x= -5
Buala!!

3x+5=2x so u subtract the 2x from 3x which is 1x and then u have 1x+5=0 and then u subtract 5 from both sides and have 1x = negative 5 so x= negative 5
