Is 4X - 3 = 19
true
false
open
My answer is true because only one number can satisfy both sides of the equatuion
I agree.
To determine if the equation 4X - 3 = 19 is true or false, we need to solve for X.
To do this, we will isolate X on one side of the equation by performing mathematical operations.
Starting with the given equation:
4X - 3 = 19
First, we can add 3 to both sides of the equation:
4X - 3 + 3 = 19 + 3
This simplifies to:
4X = 22
Next, we need to isolate X by dividing both sides of the equation by 4:
(4X)/4 = 22/4
This simplifies to:
X = 5.5
So, the solution to the equation is X = 5.5.
Since the original equation asks if 4X - 3 equals 19, we can substitute the value of X we found, which is 5.5, into the equation and check if it holds true:
4(5.5) - 3 = 19
22 - 3 = 19
19 = 19
The equation holds true since both sides are equal, so the answer is "true".
