Solve the system of equations. (1 point) 5x + y = 9 3x + 2y = 4 (−2, 5) (1, 4) (2, −1) (4, −4)
1 answer:
Heyo, the answer is (2,-1).
5x+y=9
3x+2y=4
I went ahead and multiplied the first equation by -2(so I can get rid of the y's)
-10x-2y=-18
3x+2y=4
Just simply add now
-7x=-14
Divide by -7 to get x by itself
x=2

Step-by-step explanation:
Answer:
y = -1/3x + 5
Step-by-step explanation:
y = mx + b
so y = 3, x = 6, m = -1/3
then 3 = (-1/3)6 + b
3 = -2 + b
b = 5
so y = -1/3x + 5
