Question

9. Solve the following pair of linear equation by the method of cross multiplication:
3x+y = -2, 4x+2y = -11​

Answer 1

Answer:

don't know bro sorry

Answer 2

Answer:

x=2 and y= 2

Explanation:

3x+2y=10---(1)

4x−2y=4---(2)

Using formula for cross multiplication method:

28

x =  −14 −1

​ −14x=−28

x=2

28 y  =  −14 −1

−14y=−28

y=2

Therefore, x=2,y=2
