What is the solution to the system of equations? Show all of your work for full credit.
x + 2y + 4z = -8
5x + y + 3z = 10
2x + y + z = 6

Step-by-step explanation:

Step 1: Move all terms not containing x to the right side of the equation.

Step 2: Replace all occurrences of x with −8−2y−4z in each equation.

Step 3: Solve for y in the first equation.

Step 4: Replace all occurrences of y with in each equation.

Step 5: Solve for z in the second equation.

Step 6: Replace all occurrences of z with −4 in each equation.

Step 7: The solution to the system is the complete set of ordered pairs that are valid solutions.

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.
