To determine if the equation is true, false, or open, we need to solve it for x and see if it holds true for any value of x.
Starting with the equation: 5x – 10 = 12x + 3
Combine like terms:
-10 = 7x + 3
Subtract 3 from both sides:
-13 = 7x
Then, divide both sides by 7:
x = -13/7
Since the equation is solved and has a specific solution for x, it is not an open equation. Therefore, the equation is false if we substitute x = -13/7 back into the original equation.
