It always confuses me when they make me do the baby steps

Algebra always makes things sound harder than they actually are, and weird vocabulary can mix up the steps we knew so well.

Part 1: Multiply the first equation by a 2 so that you can cancel out the y variable.

6x - 2y = 0

5x + 2y = 22

Part 2: Actually cancel out the y variables, and combine like terms.

11x = 22

Part 3: Solve for "x" by dividing both sides by 11

x = 2

Part 4: Substitute the variable "x" with the value we just solved for in the original equation.

3(2) - y = 0

6 - y = 0

Then, solve for y by adding y to both sides

6=y

Solution Set = {2,6}

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

faster, im not sure why but i know it is faster
