Question 78939
Solve these simultaneous equations using a algebric method
3x+7y=18
x+2y=5
x=           y=

1- First, multiply the 2nd equation times -3
   -3x-6y=-15
2- Add your equations
   3x+7y = 18
  -3x-6y =-15
3- Your solution should be y=3
4- Substitute 3 for y into either of the original equations
5- I'm going to use x+2y=5.
   x+2(3)=5
   x+6=5
   x=-1
6- So x=-1 and y=3
