Question

Is 4x – 3 = 19 true, false, or open?

Answer 1

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.
