Question

The steps below show the incomplete solution to find the value of x for the equation 5x − 2x − 3 = −2 + 17: Step 1: 5x − 2x − 3 = −2 + 17 Step 2: 5x − 2x − 3 = 15 Step 3: 3x − 3 = 15 Which of these is most likely the next step? A. 3x=15 B. 3x=12 C. 3x=18 D. 3x=45

Answer 1

You should try to get the x by itself. To do that move everything to the right side. we have 3x-3=15. The first step we should take to get the x by itself is adding 3 to both sides. The correct answer is C. 3x=18
