The solutions are x=0 and y= -2, if the given equations are and .
Step-by-step explanation:
The given is,
...............................(1)
.................................(2)
Step:1
To find the values of x and y, we subtract the equation (1) and (2)
( - )
Subtraction of the Eqn (1) and (2) becomes,
Substitute the value of y in Equation (2),
x = 0
Step:2
Check for solution,
Substitute the values of X and y,
-8 = -8
Both sides are equal so the values of x = 0 and y = -2 are equal.
Result:
The solutions are x=0 and y= -2, if the given equations are and .
