Question

substitution method se banao x+y=3 & 4x-3y=26

Answer 1

Here is your Answer dude
______________________________

$x + y = 3 \\ x = 3 - y \\ \\ now \: put \: the \: value \: in \: eqution \: (2) \\ 4(3 - y) - 3y = 26 \\ 12 - 4y - 3y = 26 \\ - 7y = 26 - 12 \\ y = \frac{ - 14}{7 } \\ y = - 2 \\ now \: putting \: value \: of \: y \: in \: eqution \: (1) \\ x - 2 = 3 \\ x = 5 \\ ans$

Answer 2

Hii friend,

X + Y= 3........(1)

And,

4X - 3Y = 26.......(2)

From equation 1 we get,

X + Y = 3

X = 3-Y ........(3)

Putting the value of X in equation (2)

4X - 3Y = 26

4 × (3-Y) -3Y = 26

12-4Y -3Y = 26

-7Y = 26-12

-7Y = 14

Y = 14/-7 => -2

Putting the value of Y in equation (3)

X = 3-Y

X => 3-(-2) => 3+2 => 5

Hence,

X = 5 and Y = -2.

HOPE IT WILL HELP YOU...... :-)
