Answer:
32
Step-by-step explanation:
1). 2X + 3Y = 100 multiply by 2, 4X + 6Y = 200
2). 3X + 2Y = 120 multiply by 3, 9X + 6Y = 360 Subtract eqn 1. from eqn 2. to eliminate 6Y
3). We get 5X = 160, X = 32, 64 + 3Y = 100, 3Y = 100–64 = 36, Y = 12
4). So X is the larger one = 32

Step-by-step explanation:
Acd. to question -
2x + 3y = 100........(i)
3x + 2y = 120.....(ii)
Multiplying (i) by 3 and (ii) by 2 then subtracting (i) from (ii)
6x + 9y = 300
6x + 4y = 240
5y = 140
y = 28
x = 8
