Question

Need Help Solving Literal Equations - 10 Problems

Answer 1

Answer:

Step-by-step explanation:

d=rt  We need to solve for r and to do this we need to isolate r

to isolate r we must move t to the other side of equal sign because you are multiplying  rt you will divide on the other side (cause you always do the opposite operation on the other side)

so it will look like rt/d=r and this is your answer d=rt/t

and prob. 2

21-p=2l+2w we need to isolate w to solve for w

so first move 2l to the other side and it becomes negative

21-p-2l=2w

now that we are multiplying  with 2 we need to isolate w , to do this we need

to divide 2 by all the equation on the other side

21-p-2l

_____    =W

2

2l   +   -1   +  -L   =W
