Answer:
(2, -3)
Step-by-step explanation:
These are the steps I used:
(6x+2y=6) x3 -> 18x+6y=18
(7x+3y=5) x2 -> 14x+6y=10
When you subtract the equations you get:
4x=8
x=2
Answer: 9/8
Step-by-step explanation:
The square root of this is 9/8 because when you square 9/8, you get 81/64, and when you square root it, you get 9/8.
The easiest way tho is knowing that when you square a number and square root the square, you get the same number, cuz the square root cancels the square. Does that make sense?
Anyways hope this helped!
