What on earth is 7 + √(x - 1) = 2?
I'm confused...

x = 26

Step-by-step explanation:

Let's go step by step.

Check your answer.

That clearly doesn't work, showing how it has no solution.

^The answer above explained it better than me :P

I am assuming that you are looking for x...

7 + √(x - 1) = 2

You must isolate x. To do this you must first subtract 7 to both sides:

7 - 7 + √(x - 1) = 2 - 7

0 + √(x - 1) = -5

√(x - 1) = -5

Now you must get rid of the square root. The opposite order of operation of the square root is squaring. Square both sides of the equation:

(√(x - 1) )² = (-5)²

x - 1 = 25

Now add 1 to both sides to fully isolate x

x - 1 + 1 = 25 + 1

x = 26

Now you must check that this is true:

7 + √(26 - 1) = 2

7 + √(25) = 2

7 + 5 = 2

12 ≠ 2

This is not true which means that this equation has NO solution

Hope this helped!

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
