The price of one bag of popcorn is $3.75

Step-by-step explanation:

Let,

x represent the cost of a bag of popcorn

y represent the cost of a drink.

According to given statement;

4x+12y=30 Eqn 1

x+6y=11.25 Eqn 2

Multplying Eqn 2 by 2

$2(x+6y=11.25)\\2x+12y=22.50\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 1

$(4x+12y)-(2x+12y)=30-22.50\\4x+12y-2x-12y=7.50\\2x=7.50$

Dividing both sides by 2

$\frac{2x}{2}=\frac{7.50}{2}\\x=3.75$

4x+12y=30 and x+6y=11.25 can be used to find the price of one bag of popcorn and the price of one drink.

The price of one bag of popcorn is $3.75

URGENT ! HELP ! Question is in photo below.

$\frac{3(x+5)}{2} \cdot 2=21\cdot 2$

Above step we use "Multiplication property of equality"

$3(x+5)=42$

In the above step we "Simplify on both sides of equation"

$3x+15 = 42$

In the above step we use "Distribution property"

$3x+15-15=42-15$

The above step is the result of using "Subtraction property of equality"

$3x=27$

Above step is result of "Combining the like terms"

$\frac{3x}{3} =\frac{27}{3}$

Above step is the result of using "Division property of equality"

$x=9$

Above step is result of "Simplifying fractions on either side of equation"
