−7x−6y=4 x=−3y+8 solve for x and y me asap

-7x - 6y = 4      and      x = -3y + 8

so:

    -7(-3y+8) - 6y = 4

    21y - 56 - 6y = 4

        15y = 4 + 56

        15y = 60

          y = 4    

x = -3y + 8

x = -3•4 + 8

x = -12 + 8

x = -4

191 students play sports and ninety-seven 10th graders were surveyed.

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
