Question

2(2x - 8) = x - 46 ?

Answer 1

Answer:

x = -10

Steps:

2(2x - 8) = x - 46  Multiply 2 and 2x, and multiply 2 and -8

4x - 16 = x - 46  You then have this equation

-x           -x  Subtract x from both sides

Now let me stop here.  Why are we subtracting?  Because we have variables on both sides, we subtract the least number with the variable. We have 4x and we have x.  Now, x means 1x, and 1x is less than 4x. Therefore, we subtract 1x from both sides : 4x - 1x = 3x.

3x -16 = -46  Then you get this

    +16   +16  Add 16 to both sides (if it said 3x +16 = -46, then you'd subtract)

3x = -30  You now have this

3       3  You only want x, so divide 3 from both sides

x = -10  Hope this helps!

Answer 2

Answer: X = -10

Step-by-step explanation:

Times two to the parentheses

Minus X from both sides, left with 3X-16=-46

Add 16 to both sides 3X=-30

Divide both sides by 3

Answer X=-10
