Y= 3x + 1 y= 2x - 3

When using the method called substitution, the y coordinate of the solution to the system of equations shown above is:
A. 13
B. -13
C. 11
D. -11

y= -11

Step-by-step explanation:

After rearranging equation 2, we get x= y+3/2

Sub it into equation 1

y= 3(y+3/2) + 1

y= 3y+9/2 + 1

y= 3y + 11 / 2

2y = 3y + 11

-y = 11

y = -11

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
