Answer:
First equation= x+y=53
second equation = x-y=23
revise the second equation.
x-y=23
x= 23+y (naging plus since linipat sya sa kabilang side)
we need to substitute the first equation to the x of the new equation
23+y+y=53
23+2y=53
2y=53-23
2y=30 divide both sides by 2
y= 15
now substitute this to the first equation
x+y=53
x+15=53
x=53-15
x=15
Sum: 38+15=53
Difference: 38-15=23
