Given Equations,
We have to find out Which system of equations is equivalent to the Given system of Equations.
1). System of equation are,
taking - common and transposing to R.H.S we get,
This equation is not equal to equal (2), so the option (1) is not the system of equation equivalent to given Equations.
Similarly, on checking other options,
2. system of equation,
Taking -3 common from L.H.S. we get,
.
Hence the Above system of equation is equivalent to the given system of equation.
So, there is no need to check option (3) and option (4).
Hence the correct option is (B).

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.
