Which of the following statements describes a correct method for solving the equation below?
2 answers:
30 + 2w = 2 • (w - 15)
Equation at the end of step 1 :
Step 2 :
Equations which are never true :
Solve : 2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation
Solve : w-15 = 0
Add 15 to both sides of the equation :
w = 15
You are trying to solve for "w", to do so you:
20 + 2w = 50 Subtract 20 on both sides
2w = 30 Divide 2 on both sides to get "w" by itself
w = 15
Your answer is B
