Answer:

x= 6

Step-by-step explanation:

Distribute -2 into the parenthesis.

-6x+(-20)+14x= 28

The negative sign cancels out the addition sign,

-6x-20+14x= 28

Add the variables together.

(-6x+14)

8x-20= 28

Add 20 to both sides.

8x-20= 28

  +20 +20

Divide to both sides.

<u> 8x</u>= <u>48 </u>

2       2

x= 6

Misaka solved the radical equation x – 3 = square root of 4x-7 but did not check her solutions. (x – 3)2 = square root of 4x-7^2
Minchanka [31]

Answer:

x=8 is a true solution of the radical equation

Step-by-step explanation:

we have

x-3=\sqrt{4x-7}

Solve for x

squared both sides

(x-3)^{2}=4x-7\\\\x^{2}-6x+9=4x-7\\\\ x^{2}-10x+16=0

Convert to factored form

x^{2}-10x+16=(x-2)(x-8)

The solutions are x=2 and x=8

<u><em>Verify the solutions</em></u>

For x=2

Substitute in the original equation

2-3=\sqrt{4(2)-7}

-1=1 ----> is not true

therefore

x=2 is not a true solution of the radical equation

For x=8

Substitute in the original equation

8-3=\sqrt{4(8)-7}

5=5 ----> is true

therefore

x=8 is a true solution of the radical equation
