MAHARASHTRA Class 10: Equations Reducible to Linear Form Videos | Pair of Linear Equations in 2 Variables

To convert the given linear equations to the standard form, substitute

76x − 23y = 7…(1) 

x − y = −2…(2) 

(3) × 76 

76x − 76y = −152…(3) 

(3) + (2) 

y = 3, x = 1 

x − y = 4…(1) 

x + y = 12…(2) 

(1) + (2) 

2x = 16, x = 8, y = 4
