Answer: addition and multiplication
Step-by-step explanation:
You’re going to subtract 3 from both sides (addition property of equality) and then divide both sides by 2 (multiplication property of equality).
The properties that will be used in solving the given equation is:
We are given a equation in terms of variable x as follows:
[tex]3+2x=4[/tex]
Now, in order to solve the given equation we need to follow the steps as:
1)
Adding (-3) on both the side of the equation.
This property is known as:
The addition property of equality.
i.e. the equation becomes:
[tex](-3)+3+2x=(-3)+4\\\\-3+3+2x=-3+4\\\\2x=1[/tex]
2)
Now, we multiply both side by (1/2)
This property is known as:
The multiplication property of equality.
i.e. the equation becomes:
[tex]2\times \dfrac{1}{2}x=1\times \dfrac{1}{2}\\\\x=\dfrac{1}{2}[/tex]
