When you simplify radicals, you are trying to find the simpliest form that is a radical. When you estimate the value, you are trying to find an irrational or rational number that equals the radical in question.
Answer:
3
Step-by-step explanation:
The factors of 18 = 2, 3, 3,
The factors of 72 = 2, 2, 2, 3, 3,
So the highest facor they both share is 3
4x - 3y = -11
-7x - 8y = 6
We need to cancel out one of the variables so let's multiply the first equation by 8 and the second by 3 and aim to cancel y.
32x - 24y = -88
-21x - 24y = 18
Now we subtract,
53x = -106
x = -2
3y = 4x + 11 = 4(-2) + 11 = 3
y = 1
Answer: (x,y)=(-2,1)
Check:
4(-2) -3(1) = -8 - 3 = -11, good
-7(-2) - 8(1) = 14 - 8 = 6, good
