Solve the equation for the variable. show each step of your solution process.

Step-by-step explanation:

We have equation

to solve for x we first add 3 to both side

now we need to remove square root from left side, so we square both sides

now we subtract 4 from both sides

x = 12  

Step-by-step explanation:

√(x + 4) - 3 = 1     Add 3 to each side

   √(x + 4) = 4      Square each side

       x + 4 = 16     Subtract 4 from each side

             x = 12

Check:

√(12 + 4) – 3 = 1

       √16 – 3 = 1

           4 – 3 = 1

                  1 = 1

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6

its line 2 i just added the rest or else it wouldn't let me answer
