Answer:

(-4, -1, 2)

Step-by-step explanation:

Substituting x=4y into the second and third equation gives 3y+3z=3, meaning y+z=1, and 5y-z=-7.

Adding these two equations gives 6y=-6, and thus y=-1.

Thus, z=2 and x=-4.

The solution of the given system of equations are; (-4, -1, 2)

What is a system of equations?

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

We have been given system of equations;

x = 4y

x - y + 3x = 3

2x - 3y - z = -7

Now, Substituting x = 4y into the second and third equation;

3y + 3z = 3,

y + z = 1, and 5y - z = -7.

Then Adding these two equations;

6y =-6,

thus y=-1.

Therefore, z=2 and x=-4.
