Question

Two times x is 8 more than y. The sum of x and two times y is 14. Write two equations and graph to find the value of y.

y = -6

y = 4

y = -4

Answer 1

y=4

Explanation:

I took the test.

Answer 2

y = 4

Explanation:

2x = y+ 8

x + 2y = 14

x = 14 - 2y

2 * (14 - 2y) = y + 8

28 - 4y = y + 8

y + 4y = 28 - 8

5y = 20

y = 4

x = 14 - 2*4 = 6
