I3x=1
A: Division property of equality
B: subtraction property of equality
The correct answer is A: Division property of equality.
The equation I3x=1 can be solved by dividing both sides of the equation by 3, thus isolating x on one side of the equation. This property is known as the division property of equality.
To solve the equation I3x=1, you need to isolate x.
Step 1: Divide both sides of the equation by 3 to get rid of the coefficient of x.
I3x/3 = 1/3
Step 2: Simplify the equation.
3x = 1/3
Therefore, the property used in this step is the Division property of equality (Choice A).
To solve the equation i3x = 1, we need to isolate the variable x. In this case, we want to get rid of the coefficient i3 so that x is by itself.
To do this, we can use the division property of equality, which states that dividing both sides of an equation by the same non-zero number will not change the equality.
So, to apply the division property of equality to our equation, we will divide both sides by i3.
i3x/i3 = 1/i3
This simplifies to:
x = 1/i3
Therefore, the correct option is A: Division property of equality.
