Answer:
The solution to the system of equations be:
(x, y) = (15, -25)
Therefore, the fourth system of equations i.e. 2x+y=5 and 2x – y=55 has the ordered pair (15, – 25) as its solution.
Step-by-step explanation:
Let us solve and check the 4th system of equations
2x+y=5
2x – y=55
solving the system of equations

subtracting




so the system of equations becomes

solve -2y = 50

Divide both sides by -2




Add 25 to both sides

Simplify

Divide both sides by 2

simplify

Thus, the solution to the system of equations be:
(x, y) = (15, -25)
Therefore, the fourth system of equations i.e. 2x+y=5 and 2x – y=55 has the ordered pair (15, – 25) as its solution.
