Question

Verify that 1.5, 5 is a solution to 2x-y=-1​

Answer 1

No the answer is incorrect

Explanation:

2*1.5-5=-1

3-5=-1

-2=-1

-1 and -2 are not the same

The correct answer is 2,5

Answer 2

Place the x (1.5) and y (5) values into the equation, and solve. If the statement you get is true, it is a solution.

2x - y = -1​

2(1.5) - 5 = -1​

3 - 5 = -1

-2 ≠ -1

Since this is a false statement, negative 2 is not equal to -1, the ordered pair is NOT a solution. I hope this helps and have a great day!
