Question

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

Answer 1

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

Answer 2

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
