Linear Equations (x and y)

In this video, we will be learning how to solve for one variable in terms of another in linear equations, such as solving for y in terms of x.

For Example:

\frac{3}{2}(x+y)=6

\frac{3}{2}(x+y)\cdot\frac{2}{3}=6\cdot\frac{2}{3}\leftarrow Multiply both sides by \frac{2}{3} to isolate x and y

 (x+y)-x=4-x\leftarrow Subtract x from both sides to isolate y

y=-x+4\leftarrow Write in y=mx+b form
