Let's solve your equation step-by-step.4x+12=4

Step 1: Subtract 12 from both sides.4x+12−12=4−124x=−8

Step 2: Divide both sides by 4.4x/4=−8/4x=−2

Answer:x=−2

So the missing step would be 4x=-8 so your answer is D.

Good luck mate :P

Answer:

step 2 is 4x=-8

Step-by-step explanation:

The incomplete work of a student to solve an equation is shown below:

Step 1: 4x + 12 = 4

Step 2: ?

Step 3: x = –8 ÷4

Step 4: x = –2

Given step 1 is 4x+12= 4

To get step 2 we subtract 12 from both sides

4x+12= 4

4x+12-12= 4-12

4x= -8

So missing equation in step 2 is 4x=-8
