Equations which are never true:

2.1 Solve : 6 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

2.2 Solve : a-3 = 0

Add 3 to both sides of the equation :

a = 3

One solution was found :

a = 3

Answer 2

$= 15 - 6a = - 3$

$6a = - 3 - 15$

$6a = - 18$

$a = \frac{ - 18}{6}$

$a = - 3$
