Answer:

D x+9 = 2x+1

Step-by-step explanation:

y = x+9

y = 2x+1

Substitute x+9 for y in the second equation

y = 2x+1

x+9 = 2x+1

This answers the question

To finish the problem

Subtract x from each side

x+9-x =2x-x+1

9 = x+1

Subtract 1 from each side

9-1 =x+1-1

8=x

Now find y

y = x+9

y = 8+9

y=17
