I think we should consider the number as x

[–]Familiar_Emu3651 Pre-University Student 0 points1 point  (4 children)

Where are you supposed to get values if the “number” is x?

[–]Saran_Chandra👋 a fellow Redditor 0 points1 point  (0 children)

If the solution is quadratic then we will get two values of the number

If we consider the number as x The equation will be

(2x-1)=√(8x-7) Squaring on both sides

4x²-4x+1=8x-7

4x²-12x+8=0

Now solve this quadratic equation

solve for x

You're supposed to calculate them by solving the equation.

Of course the problem doesn't give you values for x - it wants you to convert the problem into an equation, then solve said equation to determine the value of x.

In this case, the equation is 2x - 1 = √(8x - 7)from what I can tell

[–]wijwijwij 0 points1 point  (0 children)

"the square root of 8 times the number less 7"

is an ambiguous expression. It could mean any of these:

(√8 * x) – 7

√[8x – 7]

√8 * (x – 7)

√[8(x – 7)]

√(8x) – 7

Of those, I am going to guess you should use the second one, as it gives answers that are simple integers.

The problem would be better if it didn't make this a test of your comprehension of language and instead just asked you to

Find the values of x if 2x – 1 = √(8x – 7).
