2y-7=0 or 2-y=0
Y=7/2 or y= 2
The total amount they spent is the cost of pizza and 4 large drinks. This amount is also the sum of the amount of gift certificate and the cash $13.20. Let x be the price of each drink. The equation would be,
13 + 4x = 6 + 13.20
The value of x from the equation is 1.55. Thus, each large drink costs $1.55.
5 less than the product of 5 and a number y is 22. (5y - 5 = 22)
Let's try to work backwards with this.
I
f we add 5 to 22, we get 27. (5y - 5 + 5 = 22 + 5)
27 divided by 5 is 5.4. (5y ÷ 5 = 27 ÷ 5)
Therefore,
y=5.4
Now, we can check this by plugging that into the first equation.
5y - 5 = 22
(5 × 5.4) - 5 = 22
27 - 5 = 22
22 = 22
Because both sides are equal, it proves that the answer is
y = 5.4
