Chapter 1 Solving Linear Equations
1.1 Solving Simple Equations
To solve for an equations means… To isolate the variable by doing inverse opertaions
Equivalent Equations Have the same solution
The Addition Property of Equality if a = b, then a + c = b + c The Subtraction Property of Equality if a = b, then a -c = b -c
x + 7 = 2 Show your work exactly like this: Write the problem: Add same number to both sides of “=“: Write answer with box around it - 7 x = -5
The Multiplication Property of Equality If a = b, then ac = bc Division Property of Equality If a = b, then
Solve: 5x = 30 Show your work exactly like this tonight
Solve: -12x = -8
To solve an equation like: Multiply both sides of the equation by the reciprocal of the coefficient
Triangle Sum Theorem The sum of the measures of the interior angles of a triangle is 180°. A C B m A + m B +m C = 180°
