In the given sum the solution is:
the value of x=-2
the value of y=1
Step-by-step explanation:
Given:
A system equation of A is 5x-y=-11
A system equation of B is 3x-2y=-8
Solution=-2,1
Multiply the equation A by 2
10x-2y=-22
Now substitue the Equation A and Bm
10x-2y=-22
3x-2y=-8
(-) (+) (+)
----------------
7x-0=-14
Therefore
7x=-14
x=-2
Substituting x=-2 in equation A to find the y Value
5x-y=-11
5(-2)-y=-11
-10-y=-11
y=-11+10
y=1
Therefore Hence the solution is proved
x=-2 y=1
