Question

solve the following by using cross multiplication method - x/3+1=9/15​

Answer 1

Answer:

18/15 IS THE ANSWER

Step-by-step explanation:

-X/3 + 1=9/15

-X/3=9/15 - 1

-X/3 = -6/15

X=18/15=6/5

Answer 2

Answer:

$\frac{-x}{3 } + 1= \frac{9}{15} \\ \frac{-x + 3}{3} = \frac{3}{5} \\- x + 3 = \frac{3}{5} \times 3 \\ -x = \frac{9}{5} - 3 = \frac{9 - 15}{5} \\- x = \frac{ - 6}{5} \\x=\frac{6}{5}$
