Answer:
A 29 is the answer to the problem
Step-by-step explanation:
Given -
Equations
- x + y = 8
- x - y = 3
To Find -
- which pair of coordinates satisfies both equation
Now,
adding both equation, we get -
x + y + x - y = 8 + 3
2x = 11
x = 11/2
<h3>x = 5.5</h3>
Now, substituting the value of x on x + y = 8, we get -
5.5 + y = 8
y = 8 - 5.5
<h3>y = 2.5</h3>
Hence,
(5.5, 2.5) pair of coordinates satisfies both equations.
x − y = 0 = difference
x + y = 4 = sum
Can be solved by the sum and difference rule (most of the time without pen and paper)
x=(sum+difference)/2=0+4/2=2
y=(sum-difference)/2=(4-0)/2=2
