Answer :

Do you want me to explain
First expand the brackets to get: -4x+7=5x+10
Then rearrange to get all the number terms and letter terms on one side:
7-10=5x+4x 
Then simplify both sides to get: -3=9x
Rearrange to find x by itself: -3/9=x
Simplify to find the value of x: x= -1/3 or -0.333333(recurring) 

I'm not 100% sure I got this right check over to make sure!
