Question

Define :Linear Equation in three variables.​

Answer 1

Answer:

Linear equations in three variables. If a, b, c and r are real numbers (and if a, b, and c are not all equal to 0) then ax + by + cz = r is called a linear equation in three variables. (The “three variables” are the x, the y, and the z.) The numbers a, b, and c are called the coefficients of the equation.
