Practice problem
Solve the system of equations using substitution. 4x+3y=18x+2y=6\begin{gather}4x+3y=18\\ x+2y=6\end{gather}4x+3y=18x+2y=6
x=185x=\frac{18}{5}x=518 , y=65y=\frac{6}{5}y=56
x=223x=\frac{22}{3}x=322 , y=73y=\frac{7}{3}y=37
x=4x=4x=4 , y=1y=1y=1
x=3x=3x=3 , y=2y=2y=2
Type a concept, like “slope” or “photosynthesis”.
