X=y+10 and x=2y+3

solve by substitution

needing x and y

The two equations given in the question are

x = y + 10

And

x = 2y + 3

Now let us substitute the value of x in the second equation with that of the first equation. We get

x = 2y + 3

y + 10 = 2y + 3

y - 2y = 3 - 10

- y = - 7

y = 7

Now putting the value of y in the first equation, we get

x = y + 10

= 7 + 10

= 17

So the value of x comes out to be 17 and the value of y comes out to be 7.
