You multiply a number by 3 subtract 6 then add 2 the results is 20

what's the number​ ?

Let the number = x

multiply a number by 3

so, it becomes 3x

subtract 6 , so, 3x - 6

then add 2

so, 3x - 6 + 2

The result will be 20

So,

3x - 6 + 2 = 20

solve for x

3x - 4 = 20

Add 4 to both sides

3x - 4 + 4 = 20 + 4

3x = 24

Divide both sides by 3

3x/3 = 24/3

So,

x = 8

Jake is solving x^2-6x+5=0 by completing the square his steps are shown below step 1. x^2-6x=-5 step 2. x^-6x+9=-5+9 step 3. (x-
damaskus [11]

Answer:

Jake's error in step 3

Step-by-step explanation:

we have

x^{2} -6x+5=0

Complete the square

step 1

Group terms that contain the same variable, and move the constant to the opposite side of the equation

x^{2} -6x=-5

step 2

Complete the square. Remember to balance the equation by adding the same constants to each side

x^{2} -6x+9=-5+9

x^{2} -6x+9=4

step 3

Rewrite as perfect squares

(x-3)^{2}=4

Jake's error in step 3

He placed 6 instead of 3 in the left side

step 4

take square root both sides

\sqrt{(x-3)^2} =\sqrt{4}

step 5

(x-3)=\pm2

step 6

x=3\pm2

step 7

x=5 and x=1
