Solve for x

Definition: Coefficient

• A numerical factor in a term of an algebraic expression.

• A variable that represents a constant value.

• A type of equation that has no solution.

• A method for solving quadratic equations.

Example: If 2x = 10, what is x?

• x = 3

• x = 4

• x = 5

• x = 6

Solve for X: 14 = 3 + x

• 9

• 10

• 11

• 12

Solve for X: 15 = 10 + x

• 2

• 3

• 5

• 7

Definition: Isolate the variable

• To manipulate an equation to get the variable alone on one side.

• To combine like terms in an equation.

• To find the value of the variable by substituting numbers.
