To find percent error, you subtract the actual number from your estimate, take the absolute value, and divide by the actual number.
l 96 - 118 l
l -22 l
l 22 l
l 22 l / 118
0.19% (this was rounded)

Answer:
yes, your right
Step-by-step explanation:
The first equation can be written as:
2x = 5 + 3y
Substituting the second equation into the first equation and rearranging:
-4y - 16 = 5 + 3y
-21 = 7y
y = -3
Substituting y = -3 into the second equation:
x = -2(-3) - 8
x = -2
You would find the square root of 361.

x=19
