Multiply first equation by -2.

After multiplying we have the following system:
−2x−10y2x+9y=6=4

now add the two equations together to eliminate "x" from the system.
−y=10

now find "y"
y=−10

now substitute the value for y into the original equation to solve for x.
x+5(−10)=−3
x=47...   @AydenCarpenter14
