Question 506656
Jim=x
mike=y
 x+2=y (2x)=y+8
so you make them both equal to y. to make (2x)=y+8 equal to x you subtract 8 on both sdes.now since they both equal y they equal each other so your new equation would be 2x-8=x+2 you solve for x by subtracting x from both sides and then you add 8 to both sides. x=10  so jim is 10 years old.
