You can put this solution on YOUR website! 8x+y=15
There are different ways to solve this,I'll solve by substitution.
Solve eq.1 8x+y=15 for y;
Now substitute this for y in the 2nd eq.;
Now that we have x we can plug that into eq.1 to get y;
So the answer is;
Hope you understand!
You can put this solution on YOUR website! You can either solve it with elimination method or subsitution method
2x+2y=9 sub in for y
2x+2y=9 (2) ---> multiply (1) by 2
2x+2y=9 ---> nopw subbtract 1 by 2
