What is the solution to the system of equations represented by the two equations?

1 answer:

4 0

Make the two equations equal together and solve for x
(x/3) = -2x+7
multiple both sides by 3
x=-6x+21
solve for x
7x=21
x=3.
now plug in 3 into one of the equation to find your y value.
y=-2(3)+7
y=1
write your answer as a coordinate; (3,1)
