Isabel and Ruth scored a total of twenty-two points in their last basketball game scored two more points than Isabelle. How many points did Isabel score? A:2x-2=22; x=12
B:x+2=22; x=20
C:2x+2=22; x=10
D:2x+2=22; x=12

isabel is represented as x

ruth is represented as x+2

so the equation would be

x+(x+2)=22

the (x+2) is ruth. so to check if its right solve it. 2x+2=22

-2 -2

2x+20

__ ___

2 2

x=10

so now you know that isabel scored 10 goals since she was x. to figure out ruth just add 2.
