Answer:
x=3.33
Step-by-step explanation:
2x=x-10
2x+x=10
3x=10
x= 10/3
x= 3.33
Answer:
yes
Step-by-step explanation:
If you are dividing it will become 1 because 10 minus 10 equals 0. Anything to the power of 0 is 1 then you keep the base which is y so the answer is y
If you are multipling the answer will be y^10 because 10 plus 10 is 20 and you keep the base which is y
