To find the value of x and y, we need to solve the system of two equations. We can use the substitution method to solve for x and y.
Starting with the first equation:
2x - y = 8
Adding y to both sides:
2x = 8 + y
Next, we'll use the second equation to find the value of y:
2x + y = 64
Substituting the expression for 2x in terms of y from the first equation into this equation:
2x + y = 64
2(8 + y) + y = 64
16 + 2y + y = 64
16 + 3y = 64
Subtracting 16 from both sides:
3y = 48
Dividing both sides by 3:
y = 16
Now that we have the value of y, we can substitute it back into the first equation to find x:
2x - y = 8
2x - 16 = 8
2x = 24
Dividing both sides by 2:
x = 12
So the solution for the system of equations is x = 12 and y = 16.
