Solve for x
x = \frac{7}{2} = 3\frac{1}{2} = 3.5
Solve for y (complex solution)
y\in \mathrm{C}
x = \frac{7}{2} = 3\frac{1}{2} = 3.5
Solve for y
y\in \mathrm{R}
x = \frac{7}{2} = 3\frac{1}{2} = 3.5

4x+y-y=14
Combine 3x and x to get 4x.
4x=14
Combine y and -y to get 0.
x=\frac{14}{4}
Divide both sides by 4.
x=\frac{7}{2}
Reduce the fraction \frac{14}{4} to lowest terms by extracting and canceling out 2.
