SOLVING EQUATIONS AND EXPANDING BRACKETS
AIM: USE FLOWCHARTS TO SOLVE EQUATIONS A + 5 = 12 A A A = 7 3C = 12 C 3 12 C = 4
6B – 5 = 13 B B B = 3 NOW TRY THESE 1. A + 10 = B – 4 = C = A + 7 = Y – 1 = V + 3 = 37
AIM: EXPAND BRACKETS 3(A + 5)This means the same as A + 5 3A + 15 Can you see a quick way of doing this? 7(B + 3)= 7B (y - 4)= 5y (2c + 5)= 6c + 15
AIM: EXPAND BRACKETS AND SOLVE THE EQUATION 5(A + 2) = 30 EXPANDED 5A + 10 = 30 A A A = 4 FLOWCHART
BALANCING 2 AIM: To solve equations with variables on both sides.
TWO STEP EQUATIONS 1. SOLVE FOR X 3. DIVIDE BY THE NUMBER IN FRONT OF THE VARIABLE 2. DO THE ADDITION STEP FIRST.
Equations – Success if you can do these 3x = 64x + 2 = 3x + 7 x/4 = 25x – 3 = 7 + 3x x + 3 = 173(x + 2) = 12 x – 4 = 134(x + 5) = 32 3x + 4 = 253(2x –
Refresher Solving Equations x x + 5 Remember: 1. We have previously solved simple equations like the one shown and we looked at the analogy of scales.
SYSTEMS OF EQUATIONS. Substitution Method Ex. 1:2x + y = 15 y = 3x We have been using the Substitution Property in our proofs. Now we are going to use.
Aim: How do we solve equations with variables on both sides? Warm Up Warm Up Lesson Presentation Lesson Presentation Problem of the Day Problem of the.
Todays Objective To be able to find the x and y intercepts of an equation and use them to draw a quick graph.
MULTIPLICATION EQUATIONS 1. SOLVE FOR X 3. WHAT EVER YOU DO TO ONE SIDE YOU HAVE TO DO TO THE OTHER 2. DIVIDE BY THE NUMBER IN FRONT OF THE VARIABLE.

Solve Multi-step Equations Students will solve equations with multiple steps (more than two) using distributive property, combining like terms, and inverse.
Inverse You will learn: That addition is the inverse of subtraction. To check your answers by using the inverse operation. To solve simple missing number.
Arithmetic and Geometric Means OBJ: Find arithmetic and geometric means.
LO: Count up to 100 objects by grouping them and counting in 5s 10s and 2s. Mrs Criddle: Westfield Middle School.
