**Equations and Their Solutions**

Mini Lessons

2
**Objectives: Write and solve one-step linear equations in one variable**

Vocabulary: Equation: is a mathematical statement that two quantities are equal Solution: a value for a variable makes an equation true,

3
**Determining Solutions of Equations**

a + 23 = 82 for a =61 a + 23 = 82 = 82 84 = 82 60 ÷ c = 6 for c = 10 60 ÷ 10 = 6 6 = 6

4
**Examples: c + 23 = 48 for c = 35 z + 31 = 73 for z =42**

96 = 130 – d for d = 34 85 = a for a = 105 75 ÷ y = 5 for y = 15 78 ÷ n = 13 for n = 5 w + 19 = 49 for w =30 d + 27 = 81 for d = 44 g + 34= -33 for g = 67 101 = 150 – h for h = 49
