Steps Only Needed
10 (-6x+5y=-2) 6 (10x+5y=3) Distribute I did this because we need to get the x's to cancel so this way a postive and a negative value of the same number will cancel out x

I Dont Do The Steps Thats Why I Need Them
These are the steps im not giving you the answers.
Oh Ok
\[\Huge~\rm~ \begin{bmatrix}-6x+5y=-2 \\10x+5y=30\end{bmatrix} \] \[\Huge~\rm~\begin{bmatrix}-30x+25y=-10 \\30x+15y=90\end{bmatrix} \]
^thats what you get after you distribute
The x's cancel out \[\Huge~\rm~\begin{bmatrix}25y=-10 \\15y=90\end{bmatrix}\]
add the numbers 25+15= ? -10+90=?
40
and
80
40y=80 We need to divide both sides because we want to isolate x 40/40=1 therefore y =1 so just y whats 80/40?
2
Therefore y=2 Now all we do is plug in 2 in place of y that into the equation 1 \[\huge~\rm~\mathrm30x+25(2) =-10\]
CORRECT.
