The square root of 81 is 9
Step-by-step explanation:
We're going to be evaluating if we can round 2. (Values in the 10's place)
The value in the 'ones' place has to be greater than or equal to 5 in order to round up 2.
Since 8 is greater than 5, we can round up 2.

Answer:
The result gives the equation: 9x = -7
solution: (-7/9, 4/3)
Step-by-step explanation:
6 x + 2y = − 2
and
3 x − 2y = − 5
add together
6x + 3x + 2y - 2y = -2 + -5
9x + 0 = -7
9x = -7
then x = -7/9
and y = -3x - 1:
y = -3*(-7/9) - 1
y = 7/3 - 1 = 4/3
solution: (-7/9, 4/3)
-----------------------------------------
6x+2y= -2 and 3x−2y =−5
6x + 3x + 2y - 2y = -2 + -5
