Question

Solve the following pair of linear equations using cross multiplication method 21-5y = 14
x+2y = -2​

Answer 1

Step-by-step explanation:

=21-5y= 14

= 21-14=5y

= 7= 5y

=7/5=y

y ka man x+2y=-2 me rakhne par

=x+2y=-2

=x+2(7/5)=-2

=x+14/5=-2

= x=-2-14/5

=x= -10-14/5

=x=-24/5

I hope ye answer apke liye sahi hoga
