Cx/d +f =b solve for x

Archy [21]

Answer:

Depending on what the equation is,

x = (b (d + f)) / c

or

x = (d (b - f)) / c

Step-by-step explanation:

cx / d + f = b

If f is in the denominator (cx / (d + f) = b)

cx = b (d + f)

x = (b (d + f)) / c

If f is added after the fraction (cx/(d) + f = b)

cx/d = b - f

cx = d(b - f)

x = (d (b - f)) / c

vaieri [72.5K]

The correct answer is solve for y in the second equation.

Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient. ...
Step 2: Subtract the second equation from the first.
Step 3: Solve this new equation for y.
Step 4: Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x.

Please simplify this please it’s due really soon!

Step-by-step explanation:

$\frac{ {13}^{6} \div {13}^{8} \times {13}^{ - 4} }{ {13}^{ - 2} }$

You need to remember the properties of exponents: multiplication adds the exponents, division subtracts the exponents.

If you multiply two powers with the same base, the result will be the base to the sum of the powers.

If you divide two powers with the same base, the result will be the base to the difference of the powers.

In your case you will this:

${13}^{6 - 8 + ( - 4) - ( - 2)}$

That is:

${13}^{ - 4}$

Or:

$\frac{1}{ {13}^{4} }$
