domain of (4x-3)/(6-3x)
Let's evaluate the domain of 4x -36 -3x
For the expression 4x -36 -3x to be defined, we must have: 6 -3x ≠ 0
ⓘ We add 3x to both sides
6 ≠ 3x
ⓘ Both sides are divided by 3
x ≠ 63
ⓘ We simplify the fraction by dividing the numerator and the denominator by 3, their greatest common divisor: 63 = 2
▶Domain of definition:   x ≠ 2
