Question

x-5Y=11 and 2x+3y=-4
Substitution method​

Answer 1

Answer:

Step-by-step explanation:

x-5y=11

2x+3y=-4

So, x=11+5y (in first equation)

Now,

2x+3y=-4

2(11+5y)+3y=-4

22+10y+3y=-4

13y= -4-22

13y= -26

y= -26/13

therefore y=-2

Now, we will substitute the value of y in any one of the given equations(preferably the first equation because it is going to be easier)

x=11-5y

x=11-(-2)

x=11+2

x=13

Therefore x=13 and y=-2
