Answer 2

Answer:

Given that,

$x + y = 14 \: \: \: \: \: \: \: \: ...(1) \\ x - y = 14 \: \: \: \: \: \: \: \: ...(2)$

Condition,

solving by substitution method

Calculations,

by subtracting equation 2 from equation 1

we get,

$(x + y) - (x - y) = 14 - 14 \\ x - x + y + y = 0 \\ 2y = 0 \\ y = \frac{0}{2} \\ y = 0$

by substituting the value of y in equation one

we get,

$x + 0 = 14 \\ x = 14$

Final answer,

final answer of the given equation is (14,0)
