Answer:

The correct answer is x= -17/26

Step-by-step explanation:

First, what we do is expand this equation:

4(7x-1)=28x-4

and

3(2x+1)-4(x+6)=6x+3-4x-24=2x-21

Equalling this two equations:

28x-4=2x-21

Passing terms

28x-2x=-21+4  =>  26x= -17  => x= -17/26

Thus the answer is x= -17/26

What are the solutions of the equation x^4-9x^2+8=0? Use u substitution to solve.
vodka [1.7K]

Answer:

The answer is the second option

Step-by-step explanation:

Let u=x^2.

( {x}^{2} ) {}^{2}  - 9( {x}^{2} ) + 8( {x}^{2} ) {}^{0}

{u}^{2}  - 9u + 8

(u - 1)(u - 8)

u = 1

u = 8

Set this equal to x^2

{x}^{2}  = 1

x = 1

or

x =  - 1

{x}^{2}  = 8

x = 2 \sqrt{2}

or

x =  - 2 \sqrt{2}
