Thread: simple equation

Thankful for help. Now I don't get how to write this. d+8 should be the numerator, d-2 the denominator. How do i get that?

Hi



First note that because the denominator must not be equal to 0

Multiply both sides by (d-2)

d-2) = \frac94\d-2)" alt="\frac{d+8}{d-2} \d-2) = \frac94\d-2)" />

d-2)" alt="d+8 = \frac94\d-2)" />

Multiply both sides by 4

Spoiler:

Expand both sides

There is a latex tutorial somewhere. You can type this problem as I have done below and click on someone's text to see what they typed.

\frac{d+8}{d-2} = \frac{9}{4}

Multiply both sides by (d-2) to give





Then multiply by 4/5 to get your answer
