which table best represents the steps to solve the equation 8 + x over 3 = 4? (5 points)
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 β
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 β 8 the same number β8 can be added to both sides of the equation
step 2: x over 3 = β4 adding β8 and 4 on the right hand side
step 3: x = β4 β
3 the same number 3 can be multiplied on both sides of the equation
step 4: x = β12 multiplying β4 and 3 on the right hand side
step justification
step 1: x over 3 = 4 β 8 the same number β 8 can be added to both sides of the equation
step 2: x over 3= β4 adding 4 and β8 on the right hand side
step 3: x = β 4 β 3 the same number 3 can be subtracted from both sides of the equation
step 4: x = β7 simplifying β4 β3
step justification
step 1: x over 3 = 4 β 8 the same number β 8 can be added to both sides of the equation
