Question

Is (14,21) a solution to y = 2x -7

Answer 1

Yes

Explanation:

What we know:

1. x = 14
2. y = 21

Solve for y to check solution:

1. y = 2x - 7
2. Plug x in: 2(14) - 7
3. Multiply: 2(14) = 2 × 14 = 28
4. Subtract: 28 - 7 = 21

Make a conclusion:

Because they say y is 21, and we confirmed that, then the answer is yes.

I hope this helps!

Answer 2

Plug point in
21 = 2(14) - 7
21 = 28 - 7
21 = 21, true
