Answer:
The solution to the given system of equations is (-2, )
)
Therefore the values of x and y are x=-2 and 
Step-by-step explanation:
Given equations can be written as

 
 
Solving equation(2) we get
x=-2
Substitute x=-2 in equation (1) we get




Therefore the values of x and y are  x=-2 and 
The solution to the given system of equations is (-2, )

Answer:
-5 divide by 28
Step-by-step explanation:
so the question supposed be " 15-20 divided by 2(4) + 20
15-20 which is also 15 + (-20)= -5
