Answer:

step 1. you see in the problem x = 6y + 9 substitue the equation for the x variable in the first equation. so it will be 2(6y+9) - 12y = 7

step 2. solve for y. butttt in this case it looks like it can't be solved .

Step-by-step explanation:

option 3. in the steps i provided  substituted x for x equals 6y + 9 which leads you to solve y. if you want you can rearrange 2x-12y=7 to solve for y so it would be  7-2x/-12 = 7

Adult tickets to a play cost $1.75 each and student tickets cost $1.25 each. Suppose there are twice as many student tickets sol
nikitadnepr [17]

Answer: the number of adult tickets sold is 400

the number of student tickets sold is 200

Step-by-step explanation:

Let x represent the number of adult tickets sold at the play.

Let y represent the number of student tickets sold at the play.

Adult tickets to a play cost $1.75 each and student tickets cost $1.25 each. If the income from the play was $1,700, it means that

1.75x + 1.25y = 1700 - - - - - - - - - -1

Suppose there are twice as many student tickets sold as adult tickets. This means that

y = 2x

Substituting y = 2x into equation 1, it becomes

1.75x + 1.25 × 2x = 1700= 1700

1.75y + 2.5y = 1700

4.25y = 1700

y = 1700/4.25 = 400

x = y/2 = 400/2 = 200
