Question

Find the values of x and y 43 = 3x + y

Answer 1

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.

Answer 2

It is X=(43/3,0)
Y=(0,43)
