8х + 9y = 20
х= -3y

HELP ASAP

x=4, y=-4/3. (4, -4/3).

Step-by-step explanation:

8x+9y=20

x=-3y

8(-3y)+9y=20

-24y+9y=20

-15y=20

y=20/-15

simplify

y=-4/3

x=-3(-4/3)=12/3=4

Y=4/-3 X=4

Step-by-step explanation:

We must use substitution. If x is -3y, then we can either substitute all the x’s or y’s. I’ll substitute y.

8x+9y=20

8x+-3x=20

5x=20

x=4

x=-3y, so -3y=4. Y=4/-3

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

maybe showing the graph would
