Question

Which of the following problems can be solved using the equation below? x+15=2x

Answer 1

Answer:

Answer is below

Step-by-step explanation:

Subtract 2x from both sides.

$x+15-2x=2x-2x\\-x+15=0$

Subtract 15 from both sides.

$-x+15-15=0-15\\-x=-15$

Divide both sides by -1.

$\frac{-x}{-1}=\frac{-15}{-1} \\x=15$

So therefore your answer is 15
