COMPLETE THE DO NOW SILENTLY, INDEPENDENTLY, & IMMEDIATELY Solve the following equations: 1). 9Y = 27 2). B + 25 = 30 3). X – 16 = 10 4). A/3 = 21 5). 4X = 60 6). Z + 34 = 60 HERO PROBLEM: 14Y + 14 = 140

WHEN FINISHED SIT IN ACADEMIC POSTURE! Objective & EU OBJECTIVE: SWBAT solve two step equations by using inverse operations to isolate the variable. Essential Understanding: We do two-step equations the same way we do one step: identify the variable, use the inverse operations to isolate it. WHEN FINISHED SIT IN ACADEMIC POSTURE!

Work Silently & Independently; silent hands for questions/to volunteer Two Step Equations Two step equations are those which have two operations in them We solve them the same way: identify the operation, do the reverse ALWAYS do addition and subtraction before multiplication/division. It’s much easier

Work Silently & Independently; silent hands for questions/to volunteer How we write them I’ve been very particular about how the written solutions to these equations are: X + 5 = 10 -5 -5 X = 5 Its going to very important in two step equations to keep your equations careful and neat! Write the operations on both sides of the equal sign!

DURING REVIEW PUT A CHECK NEXT TO A RIGHT ANSWER OR CORRECT IT! Watch me do these Examples 1). 2X + 10 = 20 2). W/3 – 5 = 15 Operations: Operations: Inverse: Inverse: DURING REVIEW PUT A CHECK NEXT TO A RIGHT ANSWER OR CORRECT IT!

Let’s Try Together Solve the following equations: 1). 2X + 8 = 32 2). B/4 + 8 = 68 3). 4V -16 = 20 4). X/5 + 15 = 45

Do Independently Articulate and solve the following equations: 1). 4Y - 14 = 18 2). Z/3 + 9 = 21 3). 4X + 10 = 58 4). A/9 + 9 = 90

Whiteboard #1 1). 5A = -45 2). X – 6 = 10 3

Whiteboard #2 1). Y – 6 = 17 2). 3A + 6 = 9 3). 5A + 1 = 0

Whiteboard #3 1). -7B = 49 2). 9R – 9 = - 81 3). 4(X + 5) + 2 = -2

Whiteboard #4 1). X + 10 = 40 2). Y – 4 = 12 3 3). 2B + 4B – 3B = 33 4). 4X – 2X + 6X – X = 56

Whiteboard #5 1). R/6 = -3 2). 4V + 10 = 30 3). 4(T – 6) = 24 4). 3X + 2(X + 6) = -22
