We can solve the system of linear equations by substitution or elimination method.
Given equations:
1) y = x + 3
2) -4x + 4y = 28
Substitute equation 1 into equation 2:
-4x + 4(x + 3) = 28
-4x + 4x + 12 = 28
12 = 28
This is not a true statement, which means there is no solution to the system of equations. The two lines represented by the equations are parallel and do not intersect.
Solve the following system of linear equations.
y = x + 3
-4x + 4y = 28
