x + 8 = 3x
To solve the equation x + 8 = 3x, we need to isolate the variable x
To solve the equation x + 8 = 3x, we need to isolate the variable x. Let’s go step by step:
1. Simplify both sides of the equation by combining like terms:
x + 8 – x = 3x – x
8 = 2x
2. Divide both sides of the equation by 2 to isolate x:
8/2 = 2x/2
4 = x
Therefore, the solution to the equation x + 8 = 3x is x = 4.
In other words, when you substitute x with 4 in the equation, you will get a true statement: 4 + 8 = 3(4).
