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?

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)

0

step-by-step explanation:

equals the constant of proportionality.

solve for

i think the answer is b x = 1, y = 35/2
