Answer:
1) x+2y=7
+3x-2y=5
2)After adding like terms your answer is
4x-0=12
Divide the left side from the right by 4
and your x= 3.
3)Then add the x value(3) into one of the 2 equations
x+2y=7
3+2y=7, Subtract 3 from the left and right side=7-3=4
2y=4, divide by two and y= 2...
Use the elimination method..Substitute x=3 and y=2 into the second equation and you should come to the same answer...
