Answer:
No.
Step-by-step explanation:
Plug in -2 for y and 7 for x in the first equation:
x - 5y = -3
(7) - 5(-2) = -3
Simplify. Remember to follow PEMDAS.
PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (& roots)
Multiplications
Divisions
Additions

First, multiply -5 with -2:
7 + (-5 * -2) = -3
7 + (10) = -3
Next, add:
7 + 10 = -3
17 ≠ -3
(7, -2) is not a solution for the given system of equations:
