Question

-15+19 x=9+7x

Answer 1

-15 + 19x = 9 + 7x

=> 19x - 7x = 9 + 15

=> 12x = 24

=> x = \(\dfrac{24}{12}\)= 2

Answer 2

\(\text{-15+19 x=9+7x}\)

\(\Leftrightarrow\)\(19x-15=7x+9\)

\(\Leftrightarrow\)\(12x-15=9\)

\(\Leftrightarrow\)\(12x=24\)

\(\Leftrightarrow\)\(x=\dfrac{24}{12}\)

\(\Leftrightarrow x=2\)

Answer 3

\(x=2\)

Answer 4

`-15 + 19x = 9 + 7x`

`<=> 12x = 24`.
