Question

How do you solve 9x+2=8x+9

Answer 1

Try solving for the variable and get everything to one side

Answer 2

Start by moving all whole numbers to one side and all x values to the other so you would subtract 2 from each side first and be left with 9x=8x+7 and then you would subtract 8x from both sides and you would have 1x=7 and lastly you would divide each side by 1 and be left with your answer x=7     
Hope this helps and have a wonderful day :)
