Answer:

Step-by-step explanation

Hello!

3x/4 + 6=42

3x/4=42-6 = 36

3x = 36*4

3x = 144

x= 144/3 =48

3/4 of 48 = (48*3) / 4 =36

36+6=42

the original number is 48

Hey there!

To solve this, we can use division. First, lets turn $1 \frac{1}{4}$ into an improper fraction:

$\frac{5}{4}$

So, we have

$\frac{5}{4} / \frac{1}{2}$

We can multiply by the reciprocal:

$\frac{5}{4} *\frac{2}{1}$

That gives us

$\frac{10}{4} =\frac{5}{2} =2\frac{1}{2}$

Hope it helps and have a great day!
