How do you solve #x/2 = 4/7#?

Answer 1

Genesis Allen

See the entire solution process below:

Multiply each side of the equation by #color(red)(2)# to solve for #x# while keeping the equation balanced:

#color(red)(2) xx x/2 = color(red)(2) xx 4/7#

#cancel(color(red)(2)) xx x/color(red)(cancel(color(black)(2))) = 8/7#

#x = 8/7#

To solve the equation x/2 = 4/7, you can cross-multiply. Multiply the numerator of the first fraction (x) by the denominator of the second fraction (7), and multiply the numerator of the second fraction (4) by the denominator of the first fraction (2). This gives you 7x = 8. To isolate x, divide both sides of the equation by 7. The solution is x = 8/7.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
