Question

guys plzz help by substitution method​

Answer 1

= 4x = 9+y [Equation1]

$= x = \frac{9 + y}{4}$

Substituting the value of x from Equation1,

=

$\frac{9 + y}{ 4} + y = 6$

$= \frac{9 + 5y}{4} = 6$

$= 9 + 5y = 24$

$= 5y = 15$

$= y = 3$

Now, substitute the value of y in Equation1,

=

$x = \frac{9 + 3}{4}$

$x = \frac{12}{4} = 3$

Hence, x = 3

and y is also = 3
