Solving for a variable means to rewrite the equation so that the desired variable is alone on one side. So, we have to "move" all the other variables/constants in order to make this happen. We are allowed to add/subtract the same quantity from both sides, or to multiply/divide both sides by any non-zero number.
Let's start with the first example: we are given
11.
the variable is not alone on the right hand side because it is multiplied by
. We can reverse this by dividing both sides by
: the equation becomes
So, we have written the equation as , which means that
now sits alone on one side of the equation, and thus we have solved the equation for
!
Similarly, we do all the others:
12.
Subtract from both sides to get
13.
Subtract from both sides to get
Now divide both sides by to get
14.
Multiply both sides by 2:
Divide both sides by :
Answer: It is the last figure
Step-by-step explanation: when u simplify the given problem you get 1/6 so you should choose the figure with 6 pieces with 1 of them shaded because you get 1/6 when you simplify the given problem.
