5x + 12 = [ ] x+ 9

Answer 1

To solve this equation, we need to isolate the variable on one side of the equation. We can do this by performing algebraic operations.

Given: 5x + 12 = [ ] x + 9

First, let's distribute the parentheses on the right side:
5x + 12 = x + 9x + 9

Now, let's combine like terms:
5x + 12 = 10x + 9

Next, let's move all the terms with x to the left side by subtracting 10x from both sides:
5x + 12 - 10x = 10x + 9 - 10x
-5x + 12 = 9

Finally, let's isolate the variable by subtracting 12 from both sides:
-5x + 12 - 12 = 9 - 12
-5x = -3

Now, divide both sides by -5 to solve for x:
(-5x) / -5 = -3 / -5
x = 3/5

So, the solution to the equation is x = 3/5.
