Question

Answer 1

\(\dfrac{x+2}{3}=\dfrac{-12}{7}\)

\(\Leftrightarrow\dfrac{7\left(x+2\right)}{21}=\dfrac{-36}{21}\)

\(\Leftrightarrow7\left(x+2\right)=-36\)

\(\Leftrightarrow7x+14=-36\)

\(\Leftrightarrow7x=-50\)

\(\Leftrightarrow x=-\dfrac{50}{7}\)

Answer 2

7(x + 2) = -12 x 3

7x + 14 = -36

7x = -50

x = -50/7

Answer 3

(x+2)x7=-12x3

(x+2) x 7 =-36

x+2 x 7=-36 

x =-36-14

x=-50
