When you expand the equation, you will have 9x + 9=25 + x Next you have to collect like terms +x will go over the equality sign to become -x. The same applies to +9 9x - x=23 - 9 9x minus x is 8x 8x=14 Divide both sides by 8 x=14/8 You will have 1 6/8 6 is the remainder while 1 is the number of times 8 divided 14. In decimal, it will be 1.75 Hope that helped. Good luck
