Question

PLEASE HELP

Answer 1

Answer:

B. 12x + 12 = 7x + 56

Explanation:

$Given : \ \sf \dfrac{12}{ x +8} = \dfrac{7}{x + 1}$

cross multiply formula: if  $\sf \dfrac{a}{b} = \dfrac{c}{d}$  then $\sf ad = cb$

$\sf 12(x +1) = 7(x + 8)$

distribute inside parenthesis

$\sf 12x + 12= 7x + 56$

collect like terms

$\sf 12x -7x = 56 - 12$

simplify the following

$\sf 5x = 44$

dividing both sides by 5

$\sf x = 8.8$

Answer 2

Cross multiply to get
7(x+8)=12(x+1)

7x+56=12x+12

Therefore your answer is B

Hope this helped :)
