-3x+4=2(x+2)
Math equations are done in the order of precedence according to PEMDAS.
2*x= 2x
2*+2=4
-3x+4=2x+4
-3x-4=2x-4
-3x=2x+0
-3x-2x=-1x
x=-1
I think this is it but you may want a second opinion. A good way to check if it makes sense is to insert the solved x=-1 into the equation and see if it makes sense. I have checked it and my anwser makes sense.

so it wil be -3x+4=2x + 2
add 3x to both sides
4=5x + 2
subtract 2 frm both sides
5x = 2
x = 2/5

-3x+4=2x+4
add 3x to both sides
4=5x+4
subtract 4
0=5x
divide by 5
0=x
all done!

-3x+4=2x+4
-5x+4=4
-5x=0
Therefore, this equation would have no solution.
