Question

What is the value of y in the equation 5x + 2y = 20, when x

0.37
2.5
9.25
10.75

Answer 1

9.075

3.75

-13.125

-16.875

Explanation:

5x + 2y = 20

5(0.37) + 2y = 20

2y=20-1.85

y=18.15/2=9.075

5(2.5) + 2y = 20

2y=20-12.5

y=7.5/2=3.75

5(9.25) + 2y = 20

2y=20-46.25

y=-26.25/2=-13.125

5(10.75) + 2y = 20

2y=20-53.75

y=-33.75/2=-16.875
