Answer:

Y=1, X= -(4/3)

Step-by-step explanation:

Y=6X+7

3X-8Y=4

Substitute Y=6X+7

3X-8Y=4

3X-8(6X+7)=4

3X-48X-56=4

-45X-60=0, therefore 45X=-60=X=-4/3

Sub. X values in Equation

Y=6X+7

=6(-4/3)+7, therefore Y=-1

Go step by step to reduce the radical. V108 VOVO try You must answer all questions above in order to submit.

katen-ka-za [31]

To reduce the radical, you have to factorize 108.

108 is a multiple of 3, so to factorize it, you can divide it by 3

$\frac{108}{3}=36$

You can rewrite the square root as:

$\sqrt[]{3\cdot36}=\sqrt[]{3}\cdot\sqrt[]{36}$

The square root of 36 is equal to 6 so you can write the expression as:

$\sqrt[]{3}\cdot\sqrt[]{36}=6\sqrt[]{3}$
