Which of the following should be done to both sides of the equation x - 3.41 = - 19 solve the value of z?
O add 19
Osubtract 19
O subtract 3.41
O add 3.41
To solve for x, you need to add 3.41 to both sides of the equation.
To solve the equation x - 3.41 = -19 and find the value of x, you need to perform the same operation to both sides of the equation in order to keep it balanced.
In this case, you should add 3.41 to both sides.
Therefore, the correct option is:
O add 3.41
To solve the equation x - 3.41 = -19, you want to isolate the variable x to find its value. In order to do this, you need to perform the same operation on both sides of the equation. Let's go through the options:
Option A: Add 19 to both sides of the equation.
This would change the equation to be x - 3.41 + 19 = -19 + 19.
Simplifying this would give x + 15.59 = 0.
However, this does not help us solve for x because now we have x added to 15.59, and we still have a constant term on the other side of the equation.
Option B: Subtract 19 from both sides of the equation.
Doing this would give us x - 3.41 - 19 = -19 - 19.
Simplifying this would give x - 22.41 = -38.
Again, this does not help us solve for x because x is still combined with another term on the left side.
Option C: Subtract 3.41 from both sides of the equation.
Subtracting 3.41 from both sides of the equation would yield x - 3.41 - 3.41 = -19 - 3.41.
Simplifying this would give x - 6.82 = -22.41.
Once more, this does not help us solve for x because there is still a constant term on the right side of the equation.
Option D: Add 3.41 to both sides of the equation.
Adding 3.41 to both sides of the equation would result in x - 3.41 + 3.41 = -19 + 3.41.
Simplifying this would give x = -15.59.
By adding 3.41 to both sides, we were able to isolate the x variable on one side of the equation and find its value.
Therefore, the correct answer is to add 3.41 to both sides of the equation: **O add 3.41**.
