Is 8 a unique solution to the equation 3(x-6) = 3x/4
2 answers:
Answer:
yes
Step-by-step explanation:
3(x - 6) = ( multiply both sides by 4 to clear the fraction )
12(x - 6) = 3x , distribute left side
12x - 72 = 3x ( subtract 3x from both sides )
9x - 72 = 0 ( add 72 to both sides )
9x = 72 ( divide both sides by 9 )
x = 8
x = 8 is the only solution and is therefore unique
