Question

Malia solved an equation, as shown below:

Step 1: 6x = 48
Step 2: x = 48 – 6
Step 3: x = 42

Part A: Is Malia's solution correct or incorrect? If the solution is incorrect, explain why it is incorrect and show the correct steps to solve the equation.

Part B: How many solutions will this equation have?

Answer 1

subtracting would be wrong it would be dividing. Just divide 6 on both sides to get x=8
for part A

FOR PART B 
there is one solution

Answer 2

Answer:

Part A- wrong step number 2 by Malia

Part B - Only 1 solution

Step-by-step explanation:

Given steps are :

Step 1: 6x = 48

Step 2: x = 48 – 6

Step 3: x = 42

Part A:

The second step is wrong. Malia subtracted 6 from 48, but she should not have done it. She should have divided both sides by 6, to get the value of 'x' which is 8.

The correct step should be :

$6x=48$

Divide both sides by 6, $\frac{6x}{6} =\frac{48}{6}$

$x=8$

Part B:

The equation has only 1 solution.
