Question

What are the values of x and y in this linear system?

x + 2y = 12
2x + 3y = 8

Answer 1

Solve one of the expressions for either the value of Y or X and substitute back into the other equation.

Answer 2

So for example if I have the linear system,
Equation 1 : X+3Y = 2
Equation 2 : 4Y + 2X = 1

I can choose either equation and solve for the X or Y so I will choose the first and solve for X

X+3Y = 2 -----> X = 2-3Y

Solved Equation 1 for X so I will substitute my new "X" into Equation 2 like so

4Y+2(2-3Y) = 1

And now all my terms are Y's and I can solve Y for an actually number and substitute that back into any of my 2 original equations and get a value for X.

Using the same method solve your Linear system.
