Answer:
23=x-13, x=36
9+x=14, x=5
12=x+8, x=4
Step-by-step explanation:
23=x-13. You want to isolate x so you have to add 13 to both sides. x=23+13, x=36
9+x=14. You want to isolate x so you have to subtract 9 from both sides. x=14-9, x=5.
12=x+8. You want to isolate x so you have to subtract 8 from both sides. x=4.
