Answer:
X = 37
Y = 29
Step-by-step explanation:
X + Y = 66
X - Y = 8
------
Solve second equation for X
X = Y + 8
Substitute for X in first equation
Y + 8 + Y = 66
2 * Y = 58
Y = 29
___
X - 29 = 8
X = 37
X = 37
Y = 29

Answer:
x = 37 and y = 29
Step-by-step explanation:
x + y = 66
x - y = 8
solve second equation for x
x = y + 8
substitute for x in first equation
y+8 +y = 66
2y = 58
y = 29
x - 29 = 8
x = 37
x = 37 and y = 29
