Solving Equations







Equation-a mathematic statement with two expressions that have the same value.

Eg. X + 2 =3

X = Expression
2 = Equation
3 = Expression




2B + 1 = 5





c = Cup.

c + OOOO = c + 4

2c + 3 =

2 = Numerical Coefficient
c = Variable
3 = Constant

Writing Expressions-An expression can be written using a single constant,variable,or a combination of operations with constants,variables,or numerical coefficients.

2y-7
2 = numerical coefficient
y = variable
- = operation
7 = constant

Write The Equation
c + 3 = 7
4 + 3 = 7
c + OOO = OOOOOOO
OOOO + OOO = OOOOOOO

c + c + OOOO = OOOOOOOOOO
constants = 4 and 10

Home Work!!
