Given:
The equation is
[tex]-50=\dfrac{x}{3}+20[/tex]
To find:
The solution of the given equation.
Solution:
We have,
[tex]-50=\dfrac{x}{3}+20[/tex]
Subtracting both sides by 20, we get
[tex]-50-20=\dfrac{x}{3}+20-20[/tex]
[tex]-70=\dfrac{x}{3}[/tex]
Multiply both sides by 3.
[tex]-210=x[/tex]
Therefore, the solution of the given equation is [tex]x=-210[/tex].
