Question

Charlie solved an equation, as shown below: Step 1: 5x = 30 Step 2: x = 30 − 5 Step 3: x = 25 Part A: Is Charlie's solution correct or incorrect? If the solution is incorrect, explain why it is incorrect and show the correct steps to solve the equation. (6 points) Part B: How many solutions will this equation have? (4 points)

Answer 1

Answer:

A. Incorrect

B. One

Step-by-step explanation:

5 is multiplying with X. Divide 5 on both sides to eliminate 5 from left hand side.

$\frac{5}{5} x = \frac{30}{5}$

$x = 6$

PART B:

Only one solution, because if we put 'x' value anything else than 6, equation will become incorrect.
