Question

How do you solve for x in `1/4x = 3y = 4`?

Answer 1

If the question is accurate:
`color(white)("XXX")x=16`

Explanation:

If the equation really is `1/4x=3y=4`
the `(=3y)` is redundant in finding the value of `x`
`color(white)("XXX")1/4x=4`
after multiplying both sides by `4`
`color(white)("XXX")x=16`

If the first equal sign was intended to be a plus (they are on the same key on my keyboard)
`color(white)("XXX")1/4x+3y=4`
subtracting `(3y)` from both sides:
`color(white)("XXX")1/4x=4-3y`
then multiplying both sides by `4`
`color(white)("XXX")x=16-12y`

If the second equal sign was intended to be a plus
`color(white)("XXX")1/4x=3y+4`
multiplying both sides by `4`
`color(white)("XXX")x=12y+16`
