Answer:

$x=\frac{179}{3}$

Step-by-step explanation:

We are solving for $x$ in the equation:

$3x+56=235$

First, isolate the variable term by subtracting $56$ from both sides of the equation:

$3x=179$

Now, divide both sides of the equation by the coefficient of $x$ :

$x=\frac{179}{3}$

This solution for $x$ , as a decimal, would be non-terminating. If you divided $179$ into $3$ , you would get the non-terminating decimal of:

$59.66666...$

Therefore, our solution is:

$x=\frac{179}{3}$

We can check our solution by substituting $\frac{179}{3}$ for $x$ in the initial equation:

$3x+56=235$

Substitute:

$3(\frac{179}{3} )+56=235$

Simplify $3(\frac{179}{3} )$ :

$179+56=235$

Add:

$235=235$

Since both sides of the equation are equal, our solution is correct!
