Equations Chapter 7.1

What is the difference between an expression and an equation? An equation has an EQUALS sign in the problem! Expression : 4 + 7 Equation : 4 + 7 = 11 Algebraic Expression : x + 5 Algebraic Equation : x + 5 = 10

Solve each equation from the list given. 9 + w = 17 7, 8, or 9 d – 11 = 5 14, 15, or 16 2y = 4 2, 3, or 4

Find each solution mentally j + 7 = 13 j = 6 m = 13 4 + m = 17 p – 2 = 19 p = 21 b = 3 15 – b = 12 Addition can ALWAYS be solved using the OPPOSITE math, but Subtraction can’t!

Find each solution mentally Multiplication can ALWAYS be solved using the OPPOSITE math, but Division can’t!
