Find the values of x and y

43 = 3x + y

3x+y=27, when x=7

1. Replace any x in the equation with 7.

3 (7) + y=27

2. Simplify.

21+y=27

3. Solve for y.

y=27-21

y=6

4. Check your answer by inserting x=7 and y=6 into the original equation.

3 (7) + 6=27

21+6=27

27=27

Yes, it checks.

It is X = (43/3,0)

Y = (0,43)
