Question 1132467
.
<pre>
Substitute the expression for y from the first equation into the second equation.


You will get a single equation for x


{{{(-7/2)x - 39}}} = {{{(-5/3)*x-17}}}.


It is how the substitution method works in this case.


To solve the last equation, first multiply both sides by 6 to ride off the denominators.


From this point, do all the arithmetic and complete the solution on your own.
