Question

What is the value of x if 5x+65=25

Answer 1

Simplifying

5x + 65 = 25

Reorder the terms:

65 + 5x = 25

Solving

65 + 5x = 25

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-65' to each side of the equation.

65 + -65 + 5x = 25 + -65

Combine like terms: 65 + -65 = 0

0 + 5x = 25 + -65

5x = 25 + -65

Combine like terms: 25 + -65 = -40

5x = -40

Divide each side by '5'.

x = -8

Simplifying

x = -8

Answer 2

Hello !!

This is a equation of first degree and we need find the solution for the unknown (x).

$\mathsf{5x+65=25} \\\\\\\mathsf{5x=25-65} \\\\\\\mathsf{5x=-40} \\\\\\\mathsf{x=\dfrac{-40}{5}} \\\\\\\boxed{\mathsf{x=-8}}$

Now , we check the result.

$\mathsf{5x+65=25} \\\\\\\mathsf{5(-8)+65=25} \\\\\\\mathsf{-40+65=25} \\\\\\ \mathsf{25=25 \: \: \textbf{TRUE}}$

Final result : the solution for (x) is -8.
