i don't kow how to sole this equation 5x10=2x7 can u help me

5x102x+7=0
3x3=0
3x=3
x=1 
5x10=2x7
Add 10 to both sides.
5x=2x+3
Subtract 2x from both sides.
3x=3
Divide both sides by 3.
x=1
This way is the more common method although Emily did get the correct answer. 
I'm in 7th grade too but I studied this last year so:
5x10=2x7
2x 2x
3x10= 7
+10 +10 (because 10 and 7 are )
3x = 3 Then divide out
x=1
