Answer:
Solve for x in the second equation.
Step-by-step explanation:
To solve a system of equations by substition you have to solve one of the equations for X or Y and then substitute that value on the X of the other equation, if you want to avoid fractions, you can use the x of the secon equation, like this:
[tex]6x+18y=24\\6x=24-18y\\x=\frac{24-18y}{6} \\x=4-3y[/tex]
So by solving X for the second equation you avoided fractions when substituting the value for X on the first equation.
