Step-by-step explanation:
1- -7x+2=2x+2-9x
2- -7x-2x+9x= -2+2 collect the like terms and put them on separate sides (always put x on the left hand side and the others on the right hand side). and always convert + to - and reversed (for example: I put the 2x from the right to the left and changed it to -2x)
3- -9x+9x= -2+2 now work out the sum
4- 0x=0 so x=0
