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
what is the missing step 2?

a. 4x = 8
b. 4x = 16
c. 4x = –16
d. 4x = –8

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

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
