To solve for x, we need to isolate x on one side of the equation.
First, let's simplify the equation:
5x + 12 = x + 9
Subtract x from both sides to get the x terms on one side:
5x - x + 12 = 9
Combine the x terms:
4x + 12 = 9
Subtract 12 from both sides:
4x = 9 - 12
4x = -3
Divide by 4 to solve for x:
x = -3/4
Therefore, the solution to the equation 5x + 12 = x + 9 is x = -3/4.
5x+12= x+9
