Question

5 less than three times a number gives 28. Find the number​

Answer 1

Step-by-step explanation:

$let \: the \: number \: be \: x \\ three \: times \: a \: number \: is \: 3x$

$5 \: less \: than \: three \: times \: a \: number = 3x - 5 = 28$

$3x = 28 + 5$

$3x = 33$

$x = \frac{33}{3}$

$x = 11$

Answer 2

Step-by-step explanation:

$3x - 5 = 28 \\ 3x = 28 + 5 = 33 \\ 3x = 33 \\ x = 33 \div 3 = 11$
