Work Step by Step
To solve a system of Linear equations with substitution, you should:
1. Solve one of the equations for a variable
2. Substitute the new equation from step 1 into the other equation
3. Solve that equation algebraically
4. Substitute your answer from step 3 back into the first equation to find the other variable
E.G.
$x + y = 5$
$2x - y = 10$
Solve for x in the first equation
$x=5-y$
Substitute the equation of x in terms of y into the second equation
$2(5-y)-y=10$
$10-2y-y=10$
$-3y=0$
$y=0$
Substitute the value of y into the first equation to find x
$x+0=5$
$x=5$
Write out the ordered pair
$(x,y)=(5,0)$
