HOPE THIS HELPS YOU! ^_^

The value of X and Y is -2 and 5.

Given that,

  • The equation is 7x + 10y = 36 and y = 2x + 9.
  • We need to find the value of x and y.

Based on the above information, the calculation is as follows:

7x + 10y = 36

y = 2x + 9

Here we put the value of y in the first equation

So,

7x+10(2x+9)=36

7x+20x+90=36

27x+90=36

27x=-54

x= -2

Now  

y = 2(-2)+9

y =  -4  +9

y=  5

Therefore we can conclude that the value of X and Y is -2 and 5.
