Answer:

x=6/31, y=147/31. (6/31, 147/31).

Step-by-step explanation:

y=-22x+9

y=40x-3

-----------------

-22x+9=40x-3

9=40x-(-22x)-3

9=40x+22x-3

9=62x-3

62x=9+3

62x=12

x=12/62

simplify,

x=6/31

-----------------

y=40(6/31)-3=240/31-3=240/31-93/31=147/31

x=6/31, y=147/31.

How do I simplify this radical?
Yuliya22 [10]
Separate the root expression into the two numbers you found as factors, with each number now under its own square root symbol. For example, sqrt(12) = sqrt(4) times sqrt(3). 3) Keep simplifying. The square root of a perfect square becomes just a number, without theradical<span> square root symbol.</span>
