Solving an equation for algebra

2x+3=x+15

x=12.

Step-by-step explanation:

2x+3=x+15 Subtract x from both sides and subtract 3 from both sides:

2x - x = 15 - 3

x = 12.

Answer: X = 12

Step-by-step explanation: To solve this equation, we must first understand what's going on.

Since our variable in this case x appears on both sides of the equation, we want to put our x-terms together on one side of the equation and put our numbers together on the other side of the equation.

So let's put our x's together on the left side of the equation and we do that by subtracting x from both sides.

On the left, we have x + 3 = and on the right, we have 15.

X + 3 = 15

Now we want to put our numbers together on the right side of the equation and we do that by subtracting 3 from both sides.

On the right we have X and on the right we have 12

Now, we have the equation X = 12.
