What are literal equations?

A literal equation is an equation that consists of mostly variables.

EXAMPLE:

a+b=c-d

Numbers and/or coefficients can be included in the equation.

EXAMPLE:

a+2b=c+1

Literal equations can be used for a lot of things such as finding the area of a rectangle, the circumference of a circle, and the distance of something.

3. ax=c-b

1. Figure out what variable you need to isolate.
2. Cancel the other variables from one side to the other ( Use inverse operations).
3. Make sure whatever you do to one side you do to the other.

1.Multiplication and division.
2.Addition and subtraction.
3.Squaring and taking a square root

Here are some subtraction and addition problems you can try!!!

Solve for x

1. -w+m-x=h

2. l-e+x=g

3. x+e+r=l

4. b-x-r=k

5. -x-u+y=o

6. p-c+x=m

7. x+f-h=b

8. k+x+r=t

9. j-i+x=g

10. -x+e-s=o

11. v+t-x=k

12. b+f-m+x=z

13. x-p+r-a=h

14. x+r-w-d+s=e

Answer key

1. x = -h +-w + m
2. x = g - l + e
3. x = l - e - r
4. x = -k + b -r
5. x = -o - u + y
6. x = m - p + c
7. x = b - f + h
8. x = t - k - r
9. x = g - j + i
10. x = -o + e - s
11. x = -k + v + t
12. x = z - b - f + m
13. x = h + p - r + a
14. x = e - r + w + d - s
