Which table best represents the steps to solve the equation 8 + x over 3 = 4? Step Justification Step 1: x over 3 = 4 + 8 The same number +8 can be added to both sides of the equation Step 2: x over 3 = 12 Adding 8 and 4 on the right hand side Step 3: x = 12 ⋅ 3 The same number 3 can be multiplied on both sides of the equation Step 4: x = 36 Multiplying 12 and 3 on the right hand side Step Justification Step 1: x over 3 = 4 − 8 The same number −8 can be added to both sides of the equation Step 2: x over 3 = −4 Adding −8 and 4 on the right hand side Step 3: x = −4 ⋅ 3 The same number 3 can be multiplied on both sides of the equation Step 4: x = −12 Multiplying −4 and 3 on the right hand side Step Justification Step 1: x over 3 = 4 − 8 The same number − 8 can be added to both sides of the equation Step 2: x over 3 = −4 Adding 4 and −8 on the right hand side Step 3: x = − 4 − 3 The same number 3 can be subtracted from both sides of the equation Step 4: x = −7 Simplifying −4 −3 Step Justification Step 1: x over 3 = −4 − 8 The same number −8 can be added to both sides of the equation Step 2: x over 3 = −4 Adding −8 and 4 on the right hand side Step 3: x = −4 ÷ 3 The same number 3 can be divided on both sides of the equation Step 4: x = −1.33 Dividing −4 by 3 on the right hand side
