Consider the the equations:

Equation 1 is 5x - 2y - 4z = 3

and

Equation 2 is 3x + 3y + 2z = -3.

Eliminate z by copying Equation 1, multiplying Equation 2 by 2, and then adding the equations.

Equation 1 is 5x - 2y - 4z = 3

and

Equation 2 is 3x + 3y + 2z = -3.

Eliminate z by copying Equation 1, multiplying Equation 2 by 2, and then adding the equations.

When solving systems of we have at least two unknowns. A common example of a system of equations is a mixture problem. If I know that the solution I use to clean my car windows is 65% water and 35% cleaner, I have one relationship. If I also know that I only have a 3-liter spray bottle that gives me a second relationship.

Finally, solve the system of equations

Finally, solve the system of equations

Celine, Devon, and another friend want to purchase some snacks that cost a total of $7.50. They will share the cost of the snacks. Which of these statements is true?

A. An equation that can be used to find x, the amount of money each person will pay is x+3=7.5. The solution to the equation is 4.5, so each person will pay $4.50.

B. An equation that can be used to find x, the amount of money each person will pay is x+3=7.5. The solution to the equation is 10.5, so each person will pay $10.50.

C. An equation that can be used to find x, the amount of money each person will pay is x⋅3=7.5. The solution to the equation is 2.5, so each person will pay $2.50.

D. B. An equation that can be used to find x, the amount of money each person will pay is x⋅3=7.5. The solution to the equation is 22.5, so each person will pay $22.50.
