Question 990964
.
{{{system(3x+2y=25,
x-3y=1)}}}.


Express &nbsp;<B>x</B>&nbsp; from the second equation, &nbsp;x = 3y+1, &nbsp;and substitute it into the first equation. &nbsp;You will get the equation for a single unknown &nbsp;y:


3*(3y + 1) + 2y = 25.


Simplify and solve it:


9y + 3 + 2y = 25,


11y = 25 -3,


11y = 22.


Please complete the solution yourself.
