Question

solve 2x + 3y = 5 and 3x + 2y = 8 cross multiplication

Answer 1

Step-by-step explanation:

2x+3y=5..........1

3x+2y=8...........2

so adding eqn 1 and 2

2 x + 3 y = 5

3 x + 2y = 8

5x + 5y = 13........3

subtracting eqn 1 and 2

2x + 3y = 5

3 x + 2 y = 8

1 x - 1 y = 3 ....4

multiply by 5

5 x - 5 y = 15....5

now.

adding eqn 4 and 5

5x - 5y = 15

5x + 5y = 13

10x = 28

x = 28 / 10
