Answer:

y = 10x + 66

Step-by-step explanation:

I don't know if this is how you wanted me to do it, there was not enough information for me to conclude if this was the correct way to do it. but I added 9x + x and whenever there is a variable without a number in front of it the variable = 1x or whatever the variable is. So 9x + 1x= 10x and 17+49= 66 so put it together and you get y= 10x +66

Answer:

y-9x=17-----1

y-x. =49----2

2-1

y-x-(y-9x)=49-17

y-x-y+9x.= 32

8x =32

x=4

y=4+49

=53

x=4

y=53
