3x – 20y – 2 = 0 11x – 5y + 61 = 0 3x – 20y = 2 → (1) 11x – 5y = ̶ 61 → (2) 44x – 20y = 244→ (3) Equation (1) – (3) = (3x – 44x) = 2 + 244 = - 41x = 246 = [x = -6] Put x = - 6 in equation (1) -18 -20y = 2 = [y = -1] both equation intersect each other P(a,b) = P(x,y) a = 6, b = -1 on putting we get 31/41
(95.89% of 625.15 + 36.36% of 499.89) ÷ 6.02 = ? – 269.72
(124.99)² = ?
The greatest number that will divide 398,436, and 542 leaving 7, 11, and 15 as remainders, respectively, is:
1219.98 ÷ 30.48 × 15.12 = ? × 2.16
(?)2 + 6.113 = 25.92 – 19.03
(23.99)2– (17.99)2+ (1378.98 + 44.99) ÷ ? = 608
