Question

Solve the equations by Cross Multiplication method 2x + y = 5 and 3x + 2y = 6

Answer 1

Answer:

2x-3x+y=5+6

x+y=11

=11xy

Answer 2

Step-by-step explanation:

2x +y =5 (1)

3x + 2y = 6 (2)

multiply eq 1 by 3 and eq 2 by 2

6x + 3y = 15 (3)

6x + 4y = 12 (4)

subtract eq 4 from 3

0+(-y)= 3

y= -3. (Ans:1)

now put value of y in eq (1)

2x + y = 5

2x - 3 = 5

2x = 5+3= 8

X= 8/2

x= 4. ( Ans : 2)

{X = 4, Y = -3} S.S
