2. Solve the system of three linear equations in three variables shown below using an appropriate method.
5z = 2y
4y= 2 - x
3x + 2y = 5z + 12
Which set of points, (x, y, z), represents the solution to the system of three
linear equations in three variables?

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

hope it

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

your answer is -9

step-by-step explanation:

10 - 8 = -2

  8 - 6 = -2

etc, so -2 is the common difference
