Question

What is the solution to the equation? 3(x - 4) < 6

Answer 1

$3(x - 4) \ \textless \ 6 \\ \\ x - 4 \ \textless \ \frac{6}{3} \\ \\ x - 4 \ \textless \ 2 \\ \\ x \ \textless \ 2 + 4 \\ \\ x \ \textless \ 6$

The final result is: x < 6.

Answer 2

3(x-4) < 6
3x - 12 < 6
Change < this symbol into =, temporarily
3x - 12 = 6
3x = 6 + 12
3x = 18
X = 18 : 3
X = 6
