Answer:
1 × (3x + 2y = 12)
2 × (4x - y = 5)
3x + 2y = 12
+ (8x - 2y = 10)
= 11x = 22
divide both sides by the coefficient of 'x' (11)
Therefore x = 2
put (x = 2) in equation 1
3(2) + 2y = 12
6 + 2y = 12
2y = 12 - 6
2y = 6
divide both sides by the coefficient of 'y'(2)
Therefore y = 3
She isn't correct. 43 is a 2-digit odd number but it isn't composite. It's a prime number.
