Solve y-5=x and x=-2-y

Answer 1

HI Margaret,

Your question: Solve y-5=x and x=-2-y

You have a "Systems of Equations" problem.

You have 2 unknowns, x and y.

You have 2 equations (They are the equations of a line)

You can solve with

1. Graphing and finding where the lines intersect
2. Using substitution
3. Using Elimination.

I'll use substitution

y-5=x

x=-2-y

y - 5 = (-2-y) // I substituted equation 2 for x in equation 1

y = -2 -y +5

2y = 3

y= 3/2

x = -2-y

x = -2-3/2

x = -7/2

Solution (-7/2, 3/2)
