(show your work 1 point) (correct answer 1 point)

Equation B: 4x - 3y = 8

2

Equation A: 5x + 9y = 10

3 answers

Work:

4x - 3y = 8
5x + 9y = 10

Multiply equation A by -4:

-20x - 36y = -40

Add equations A and B:

-16x = -32

Divide both sides by -16:

x = 2

Substitute x = 2 into equation A:

5(2) + 9y = 10

10 + 9y = 10

9y = 0

y = 0

Answer: x = 2, y = 0
