Well just do 16.50 divided by 3 to get the unit price o each pizza
(gets calculator)
which is 5.5 which mutiplyed by 3 will = 16.50
﴾͡๏̯͡๏﴿ O'RLY?
X=-7 divide both side by 3. Any expression divided by itself equals 1. Dividing a positive and a negative equals a negative. Calculate the quotation. Then you get X=-7
We have the system of equations:
3x + 5y = 10
x + 5y = 2 => x = 2 - 5y
__________________
3*(2 - 5y) + 5y = 10
6 - 15y + 5y = 10
-4 = 10y
y = -4/10 = -2/5 => x = 2 - 5*y = 2 - 5*(-2/5) = 2 + 2 = 4
The correct answer is x = 4.
