mx-ny = m²+n²
⇒ mx - ny = m² + n² +2mn - 2mn
⇒ mx - ny = (m + n)² - 2mn [identity a² + 2ab +b² = (a+b)²] → 1
x + y = 2m → 2
Substituting eq. 2 in eq. 1.
mx - ny = (m + n)² - (x + y)n
- (x + y)nmx - ny = (m + n)² - nx - ny
Addding ny to both sides, you get:
Addding ny to both sides, you get:mx = (m + n)² - nx
- nxmx + nx = (m + n)²
x(m + n) = (m + n)²
Dividing both sides by (m + n), you get:
Dividing both sides by (m + n), you get:x = m + n
Dividing both sides by (m + n), you get:x = m + nSubstituting x = m + 2 in eq. 1.
Dividing both sides by (m + n), you get:x = m + nSubstituting x = m + 2 in eq. 1.(m + n) + y = 2m
y = 2m - m - n
y = 2m - m - ny = m - n
Therefore, x = m + 2, y = m - n
