To solve for x, you need to isolate it on one side of the equation.
Starting with the equation:
5x + 10 = x + 9
First, subtract x from both sides:
5x - x + 10 = x - x + 9
4x + 10 = 9
Next, subtract 10 from both sides:
4x + 10 - 10 = 9 - 10
4x = -1
Finally, divide both sides by 4 to solve for x:
4x/4 = -1/4
x = -1/4
5x+10= x+9
