Question

Y=x-5
x+y=-1
What is the solution to the system of equations

Answer 1

x = 2

y = -3

Explanation:

y = x - 5

x + y = -1

To solve the given system of equations, we can use the method of substitution.

That is, you can replace y with ( x - 5 ).

x + y = -1

x + (x - 5 ) = -1

x + x - 5 = -1

Combine like terms.

2x - 5 = - 1

Add 5 to both sides.

2x = - 1 + 5

2x = 4

Divide both sides by 2.

x = 2

And now let us find the value of y by replacing x with 2.

y = x - 5

y = 2 - 5

y = -3
