Solve for x. 3/4 = x/12 <br> I need work shown to

marta [7]

$\frac{3}{4} = \frac{x}{12}$

To solve for x you have to bring the 12 to the other side

How do we do this?

Well if you think about it this is technically what the equation shows

$\frac{3}{4} = x * \frac{1}{12}$

This means to isolate x you can multiply both sides by 12 and that will cancel $\frac{1}{12}$ from the right side

$\frac{3}{4} * 12 = x * \frac{1}{12} * 12$

$\frac{36}{4} = x * 1\\\frac{36}{4} = x$

$\frac{36}{4}$ can be further simplified to...

^^^This is the answer

Check:

3/4 = 9/12

3/4 = 3/4

Hope this helped!

Determine whether the statement below is always, sometimes, or never true. Justify your reasoning.

zloy xaker [14]

This is sometimes true I say this because if u substitute your answers that can be different or can be the same.
for ex. x=6 y=6; 6-3 and 6-3 will be the same but if x= 10 and y=15; 10-3 and 15-3 would give you different answers
