Question

x+5y=8 2x-3y=-10 solve it by substitution method​

Answer 1

Answer:

x=-2, y=2

Step-by-step explanation:

We have,

x+5y=8

=> x=8-5y   ...(i)

And,

2x-3y=-10  ...(ii)

Putting value of equation (i) in (ii)

We get

2(8-5y)-3y=-10

=> 16-10y-3y=-10

=>13y=26

=>y=2   ...(iii)

Now, putting value of yin equation (i),

We get,

x=8-5(2)

=>x=8-10

=>x=-2  ...(iv)
