5x+12= x+9

1 answer

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.
