Question

The steps below show the incomplete solution to find the value of x for the equation
5x − 3x + 4 = −4 + 20:
Step 1: 5x − 3x + 4 = −4 + 20
Step 2: 5x − 3x + 4 = 16
Step 3: 2x + 4 = 16 Which of these is most likely the next step?

A 2x=4
B 2x=12
C 2x=20
D 2x=18

Please explain with steps

Answer 1

The answer would be B. Step 4 would be to subtract the +4 on both sides of the equation. You would have 2x + 4 - 4 = 16 - 4. This gets simplified to 2x = 12. Hope this helps!

Answer 2

B) 2x=12

This is because for the equation, x = 6
A) x = 2
B) x = 6
C) x = 10
D) x = 9
