ALGE-MATE KIT Solving one-STEP linear equations
What is a linear equation? A linear equation is an algebraic number sentence that makes a straight line when you graph it. Here’s an example: 3x+4=10
How do we solve them? Solving a linear equation means finding out what value the variable (letter) represents. For example: What does x represent in the equation 2x - 5 = 1?
to solve linear equations, we can use ‘undoing steps’! UNDOING STEPS = OPPOSITE OPERATIONS
solving one-step linear equations
EXAMPLES x + 7 = 15 -7 -7 x = 8 x × 4 x = 12 3x = 15 ÷3 x = 5 ÷3 4 = 3 × 4
