<h3>Solution :</h3>

$\sf \dfrac{6x+4}{3} = \dfrac{5x-5}{8}$

By cross multiply, we get

$\sf : \implies (6x+4) \times 8 = (5x-5) \times 3$

$\sf : \implies 48x+32 = 15x-15$

$\sf : \implies 48x+32 - 15x + 15= 0$

$\sf : \implies 33x + 47 = 0$

$\sf : \implies 33x = -47$

$\sf : \implies x = \dfrac{- 47}{33}$

Therefore, answer is $\sf x = \dfrac{- 47}{33}$

Joelle is working on a school report in a word processor. She wants to place a figure which is 13.09 \text{ cm}13.09 cm13, point

Subtract 13.09 from 21.59 giving you 8.5. Since the amount of space on both the left and right margin have to be equal you would divide by 2 to get 4.25 on the left margin as well as the right.
