Question

The steps below show the incomplete solution to find the value of x for the equation

6x − 2x − 5 = −6 + 21:

Step 1: 6x − 2x − 5 = −6 + 21
Step 2: 6x − 2x − 5 = 15
Step 3: 4x − 5 = 15

Which of these is most likely the next step?



4x=10
4x=3
4x=45
4x=20

Answer 1

The next step should be 4x=20~

Answer 2

in the step 3 you can add 5 on both sides so you gonna have :
4x-5 = 15
+5 +5 ⇒ 4x = 20 so thats the next step :))
