Question

Solve For X ans Y using substitution method x+y=4,4x-3y=26​

Answer 1

Question :

Solve For x ans y using substitution method:

1 : x + y=4 and 4x-3y=26.

Solution :

=》 Here we have two equations :

x + y = 4 _____ eq 1

4x - 3y = 26 _____eq 2

=》In Equation 1

x + y = 4

x = 4 - y

=》 From here Putting the Value of x In equation 2 .

4 ( 4 - y ) - 3y = 26

16 - 4y - 3y = 26

- 7 y = 26 - 16

y = - 10 / 7

Put y in equation 1 ,

x + - 10 / 7 = 4

x = 4 + 10/7

x = 38 / 7

So We got X = 38 / 7 and y = - 10 /7
