use substitution to solve the system
5x+2y=27
y=2x+11
x=
y=

Use substitution means replace y in the first equation with what y equals in terms of x.
5x + 2(2x+11) = 27
Next, multiply by 2 to remove ( )
combine like terms
continues to solve for x.
Find y by replacing x with your answer for x in y = 2x+11
Always...check x and y in both equations.
