Question

1)
Solve the following equations, 5x4 - 22x+8 = 0​

Answer 1

Answer:

$\Large\boxed{X=4}$

Step-by-step explanation:

Isolate by the x on one side of the equation.

Given:

5x-4-22x+8=0 (Find the value of x on one side of the equation.)

Solutions:

First, multiply.

$\displaystyle 4*5=20$

$\displaystyle 20x-22x+8=0$

Secondly, add the numbers from left to right.

Add similar elements to by the numbers from left to right.

$\displaystyle 20-22=-2$

$\displaystyle -2x+8=0$

Thirdly, subtract by 8 from both sides.

$\displaystyle -2x+8-8=0-8$

Solve.

$\displaystyle 0-8=-8$

$\displaystyle -2x=-8$

Then, divide by -2 from both sides.

$\displaystyle \frac{-2x}{-2}=\frac{-8}{-2}$

Solve.

Divide the numbers from left to right.

$\displaystyle -8\div-2=\boxed{4}$

$\Large\boxed{X=4}$

As a result, the solutions is x=4, which is our answer.

Answer 2

AnswEr :

➟ 5x4 - 22x + 8 = 0

➟ (5x × 4) - 22x + 8 = 0

➟ 20x - 22x + 8 = 0

➟ -2x + 8 = 0

➟ 8 = 2x

➟ x = 4
