Solve the system of linear equations. what is the value of y? 9x−6y=15 6x+21y=60

y = 5

y = 2.2

Step-by-step explanation:

For the first one:

9x = 9 x1 = 9

9 - 6 = 3

3y = 15

15 ÷ 3 = 5

y = 5

For the second one:

6x = 6 x 1 = 6

6 + 21 = 27

27y = 60

60 ÷ 27 ~ 2.2

y = 2.2

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
