One-Step Equations With Variable

a symbol for an unknown value; usually a letter (such as a, x, or y) is the symbol used

• constant

• variable

• coefficient

• term

To solve an equation, the goal is to __________ the variable on one side.

• Evaluate

• Leviate

• Isolate

• Reciprocate

a mathematical sentence stating that two expressions are equal

• term

• coefficient

• equation

• variable

2x - 3 + 4x = 27

• 12

• 4

• 5

• 15

Solve the equation:
-5x = 25

• x = 20

• x = -20

• x = -5

• x = 5

4x + 10 = -26

• 4

• -4

• -9

• 9

The objective when solving an equation is to....

• isolate the variable.

• check the solution.

• guess and check.

• Combine Like Terms.

-15 = 5a +12- 2a + 6

• -11

• -3

• 10

• 7

The goal of solving a one, two, or multi-step equations is to:

• Find the coefficient

• Find the value of the variable

• Find the constant
