What is the y-coordinate of the solution for the system of equations? {x-u=12{27+3y=2x enter your answer in the box.

The y-coordinate of the solution for the system of equations is -3

Step-by-step explanation:

* Lets explain how to solve the system of equations

- We can solve the system of equations by the elimination method

# Eliminate one of the two variables by equating the coefficient of it

  in the two equations with opposite signs

# Add the equations and find the value of the other variable

# Substitute its value in one of the two equations to find the

  eliminated variable

* Lets solve the problem

- The system of the equations are:

∵ x - y = 12 ⇒ (1)

- Lets arrange the terms in the other equation

∵ 27 + 3y = 2x ⇒ subtract 3y from both sides

∴ 27 = 2x - 3y ⇒ switch the two sides

∴ 2x - 3y = 27 ⇒ (2)

- Multiply equation (1) by -2 to eliminate x

∴ x(-2) - y(-2) = 12(-2)

∴ -2x + 2y = -24 ⇒ (3)

- Add (2) and (3)

∵ 2x - 3y = 27 ⇒ (2)

∵ -2x + 2y = -24 ⇒ (3)

∴ -y = 3 ⇒ multiply both sides by -1

∴ y = -3

* The y-coordinate of the solution for the system of equations is -3

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
