i don't kow how to sole this equation 5x-10=2x-7 can u help me
Add 10 to both sides.
Subtract 2x from both sides.
Divide both sides by 3.
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:
+10 +10 (because -10 and -7 are -)
3x = 3 Then divide out
