Answer :
Step by Step Solution:
- Move 2y in the second equation to the left side to get [tex]x+y =25\\x-2y=-2[/tex]
- Then subtract the second equation from the first [tex]x+y =25\\-(x-2y=-2) \\[/tex]
- By subtracting like terms you eliminate x and you are left with y+2y = 3y and 25+2 = 27
- Which is the equation 3y=27.
- Divide 3 from both sides to get y=9.
- Substitute y=9 back into the first equation to get x+9= 25.
- Subtract 9 from both sides to have x=16
- (16, 9) is your solution
