When there are two variables ('x' and 'y'), then you need two equations
in order to find a solution.

If you only have one equation with 2 variables, then there are an infinite
number of solutions.

Here are a few solutions to this particular equation:

x = 0,   y = -31
x = 1,   y = -29
x = 2,   y = -27
x = 3,   y = -25
x = 15,   y =   -1
x = 20,   y =    9
x = 30,   y =   29
x = 40,   y =   49
x = 50,   y =   69
x = 100, y = 169

Now that you have these 10 solutions,
there are only an infinite number of others.

How do you solve substitution to solve the sytem <br> x+y=2<br> -2x+y=2

lord [1]

So you want to make one of the equations equal to one of the placeholders exg y=x+3

so we have
x+y=2 and
-2x+y=2

I chose to make -2x+y=2 equal to y so
-2x+y=2
add 2x to both sides
y=2+2x

subsitute 2+2x for y in x+y=2
x+2+2x=2
add like terms
3x+2=2
subtract 2 from both sides
3x=0
x=0

subsitute x=0 in x+y=2
0+y=2
y=2

x=0
y=2
