Solve the equation by adding like terms, (5y-3y) so that you have 2y-6=-20, then add 6 to 20, 2y=-20, then divide 20 by 2. y=10.

First, add 6 to both sides to combine like terms. Now you have 5y=3y-14. Then, you need to subtract 3y from both sides to finish combining like terms. You will now have 2y=-14. Divide both sides by 2 to get y alone (solve for y). Now you have your answer. y=-7.

Concert tickets cost $15 for general admission, but only $9 with a student ID. Ticket sales total $450. Write and graph an equat
aliina [53]

The equation that models the situation is 15x + 9y = 450

The x-intercept is (30, 0) and the y-intercept is (0, 50)

Given the following parameters:

  • Cost of concert tickets for general admission= $15
  • Cost of a ticket for those with student ID = $9

Given that the total sales is $450, the equation that models this situation will be expressed as:

  • 15x + 9y = 450

where:

x is the those that admitted generally

y are those with student ID

<u />

<u>Get the x-intercept.</u>

This is a point where the y-axis is zero

15x + 9y = 450

15x + 9(0) = 450

15x = 450

x = 450/15

x = 30

Thee x-intercept is (30, 0)

<u>Get the y-intercept.</u>

This is a point where the x-axis is zero

15(0) + 9y = 450

0 + 9y = 450

9y = 450

y = 450/9

x = 50

The y-intercept is (0, 50)
