Question

solve by y value
13-y/3 = 9+x/3​

Answer 1

Answer:

y=12-x

Step-by-step explanation:

As far as i understood, you might've meant solve in terms of y.So..

13-y/3=9+x/3

39-y /3=27+x /3(LCM)

39-y=27+x(Remove the 3 from both sides)

-y=-39+27+x

-y=-12+x

y=12-x(Multiply both sides by - )

$\large\bf\color{navy}{To~solve:}$

$\tt{~~~~~~~~13-{\large{\frac{y}{3}}}=9+{\large{\frac{x}{3}}}}$

$\tt{: \longrightarrow {\large{\frac{39-y}{3}}={\frac{27+x}{3}}}}$

$\tt{: \longrightarrow 3(39-y)=3(27+x)}$

$\tt{: \longrightarrow 117-3y=81+3x}$

$\tt{: \longrightarrow -3y=81+3x-117}$

$\tt{: \longrightarrow -3y=-36+3x}$

$\tt{: \longrightarrow 3y=36-3x}$

$\tt{: \longrightarrow y={\large{\frac{36-3x}{3}}}}$

$\tt{: \longrightarrow y={\color{navy}{\underline{\boxed{\tt~12-x~}}}}}$
