Respuesta :
x+y=100
x-y=26
add them equations
x+y=100
x-y=26 +
2x+0y=126
2x=126
divide both sides by 2
x=63
sub back
x+y=100
63+y=100
minus 63 both sides
y=37
the numbers are 63 and 37
x-y=26
add them equations
x+y=100
x-y=26 +
2x+0y=126
2x=126
divide both sides by 2
x=63

x+y=100
63+y=100
minus 63 both sides
y=37
the numbers are 63 and 37
