First no. = x
Second no. = y
Equation Formation
x + y = 6..........equation(i)
x - y = 10...........equation (ii)
x = 6 - y
6 - y - y = 10
6 - 2 y = 10
-2 y = 10 -6
-2 y = 4
y = -2
x = 6 + 2
x = 8
Answer = 8 , -2
You have 28 meters of fence to make 3 sides.
28/3 = 9.3333
The pen will be 9.3333 by 9.3333 meters
Top 1. Substitute 3y on both sides of the equation.
Bottom 2. Substitute 2y on both sides of the equation
3y and 2y cancel
Divide x by 4 and 26 by 4.
Is there die points on a graph or decimal?
I have not done this for years but there is many calculators that can show you step by step online. I recommend using these
Probably 2561 but since area equal r^2 I thought it would be 3217
