Answer:
x=2.5906672908862554,−0.2573339575529219
Answer:
Step-by-step explanation:
So the division property states that if both sides of an equation are equal and whenever you divide both sides of that equation by the same number they should stay equal. Example
12=12 right? so if I divide both 12 and 12 by 3 I should get 3=3
We use this to solve for variable such as x
So new example lets take
5x=25
Since both sides are equal I can divide by the same number and should get an equal number right? So lets divide by 5 on both sides. 5x divided by 5 equals x and 25 divided by 5 equals 5 so my new equation is
x equals 5 or x=5.
If I plug my x=5 back into the equation they should be equal so lets see...
5(5)=25
25=25
And it checks out :)
Okay. For these types of problems, you must do order of operations (PEMDAS). Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction. Mind you that you do these steps from left to right, and multiplication and division is done from left to right. Same thing with addition and subtraction. With that being said, here are your answers if you do the expressions correctly.
1. 12
2. 106
3. 42
