Hello, could somebody solve this to find the values for P_{1 }and P_{2} for me and show how they have worked it out I am struggling a bit with it. Thanks

2P_{1 - }5P_{2 }= -6
-P_{1 }+ 3P_{2 }= 4
Using your variables, Multiply the second equation by 2 to get
-2P_{1}+ 6P_{2}= 8 and add the first equation
2P_{1}- 5P_{2}= -6
P_{2}= 2. With P_{2}= 2, the second equation is -P_{1}+ 3(2)= -P_{1}+ 6= 4. So -P_{1}= 4- 6= -2 and P_{1}= 2.
