Answer

x=1/5, y=-4/5, z=1/2

Work Step by Step

You first get the numbers and simplify them, after that you can just move the letters around and do the calculation, after that, you get the answer. Ex: A linear equation in variables has the form The coefficients are real numbers, and a constant term is a real number. The number is the leading coefficient and is the x leading variable. a1+x1 + a2+x2 + a3+x3 + .... + An+Xn=b
