To solve for x in the equation 5x + 10 = 30 + 15x, you need to isolate x on one side of the equation. Here’s a step-by-step approach:
- Start with the original equation:
- Move the terms involving x to one side:
- Next, isolate the constant term:
- Finally, solve for x:
5x + 10 = 30 + 15x
Subtract 15x from both sides to get:
5x – 15x + 10 = 30
This simplifies to:
-10x + 10 = 30
Subtract 10 from both sides:
-10x = 30 – 10
-10x = 20
To find x, divide both sides by -10:
x = 20 / -10
x = -2
Therefore, the solution to the equation 5x + 10 = 30 + 15x is:
x = -2
This process demonstrates how to manipulate an equation step by step to find the value of the variable.
