Answer 2

ANSWERS:

$\Huge\boxed{\mathsf{\Rightarrow X=\frac{115}{2}=57.5 }}$

EXPLANATIONS:

GIVEN:

You have to isolate by the x on one side of the equation.

SOLUTIONS:

First, subtract 65 from both sides.

$\displaystyle \mathsf{2x+65-65=180-65}$

Solve.

Subtract.

$\displaystyle \mathsf{180-65=115}$

$\displaystyle \mathsf{2x=115}$

Next, divide by 2 from both sides.

$\displaystyle \mathsf{\frac{2x}{2}=\frac{115}{2}}$

Solve.

Divide.

$\displaystyle \mathsf{115\div2=\boxed{57.5}}$

$\Large\boxed{\mathsf{\Rightarrow X=\frac{115}{2}=57.5 }}$

Furthermore, the final answer is x=115/2=57.5.
