equivalent form of this equation x/12 -7=x/4

options

x-7=3x
x-74=12x
x-84=3x

The correct answer is 3. x-84=3x

That's because
X/12 - 7 = x/4 is also (x-84)/7 = x/4 and when you cross multiply it you get (x-84)4 = x 7
4x-336=7x
-3x = 336
x = 336/-3
x = -112

Answer:

Option 3. \(x-84=3x\)

Step-by-step explanation:

we have

\(\frac{x}{12}-7=\frac{x}{4}\)

simplify

Multiply by \(12\) both sides

\(12(\frac{x}{12}-7)=12(\frac{x}{4})\)

\(x-7*12=3x\\ \\x-84=3x\)

\(3x-x=-84\\ 2x=-84\\ x=-42\)

therefore

the answer is the option 3
