Answer:
To determine if the equation 4x - 3 = 19 is true, false, or open, we need to solve for x.
To isolate x, we add 3 to both sides of the equation:
4x - 3 + 3 = 19 + 3
4x = 22
Then, we divide both sides of the equation by 4:
4x/4 = 22/4
x = 5.5
Since x = 5.5 satisfies the equation, the statement 4x - 3 = 19 is true.
