2x - 4y = 32
2x - 8y = 48
2x - 2x - 4x - (-8y) = 32 - 48
4x = -16
x = -16 ÷ 4
x = -4
substitute your value of x into any of the original equations
2 (-4) - 4y = 32
-8 - 4y = 32
-4y = 32 + 8
-4y = 40
y = 40 ÷ -4
y = -10
Here is a little tip for this: The unit above cancels the unit below. So in this problem you are asked to convert pounds to ounce. So your equation will look like this.
ounce = 2.93 pounds

Your ratio should involve the conversion factor. So 16 and 1 is involved canceling A and D. Then, Notice that you started with poubls. Then the ratio must have pounds at the bottom to cancel the units leaving ounces.
