Final answer:

After substituting x=4, y=-3, and z=5 into the given equations, we find that each equation holds true. Therefore, the values (4, -3, 5) are solutions to the system of equations.

Step-by-step explanation:

To determine if the given set of values ((4, -3, 5)) is a solution to the system of equations, we must substitute x=4, y=-3, and z=5 into each equation and see if they satisfy all the equations. Starting with the first equation 4x + 2z = 26, when we substitute the values we get:

  • 4(4) + 2(5) = 16 + 10 = 26, which is true.

For the second equation 5y - z = -20, substituting the values gives:

  • 5(-3) - 5 = -15 - 5 = -20, which is also true.

Finally, for the third equation -x - 3y + 4z = 25:

  • -4 - 3(-3) + 4(5) = -4 + 9 + 20 = 25, this holds true as well.

Since all three equations are satisfied by the given values, the answer to the question is Yes, the values (4, -3, 5) are indeed solutions to the system of equations.
