Linear equation: 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 coefficient of the equation. The
number r is called the constant of the equation
y(a-b)=c(y+a)
ya-yb=cy+ca
ya-yb-cy=ca
y(a-b-c)=ca
[tex]y=\frac{ca}{a-b-c}[/tex]
case 1:
if either C and a are zero the y is zero,
case 2:
if
[tex]c\neq 0 \\a\neq 0\\y\neq 0[/tex]
