Chapter 1 - Systems of Linear Equations - 1.1 Introduction to Systems of Linear Equations - 1.1 Exercises - Page 11: 59

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

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
