15 + 3x=45
Subtract 15 from both sides.
Then divide both sides by 3.
To solve the equation 15 + 3x = 45, we need to isolate the variable x.
Step 1: Start by subtracting 15 from both sides of the equation:
15 + 3x - 15 = 45 - 15
3x = 30
Step 2: Divide both sides of the equation by 3 to solve for x:
3x/3 = 30/3
x = 10
Therefore, the solution to the equation 15 + 3x = 45 is x = 10.
