use the row operations tool to solve the following system of equations, obtaining the solutions in fraction form.
10x + 5z = 5
8x + 2y + z = 4
3x + 3y - 4z = 5
2x - 2y + 4z = 1
give the values for x, y, and z with the fractions reduced to lowest terms (for example 4/7 rather than 8/14).
x =
y =
z =
