Question

3x-2y=7
4x-3y=9
solve the value of x and y in the given simultaneous equation

Answer 1

x=13 and y=16 hope its correct

Answer 2

Answer:

The solution of the equation 3x - 2y=7  , 4x - 3y=9 are (3,1 ) .

Step-by-step explanation:

As the equation is given in the form

3x - 2y=7

4x - 3y=9

Multiply 3x - 2y=7  by 3 .

Equation becomes

9x - 6y = 21

Multiply 4x-3y=9 by 2

Equation becomes

8x - 6y = 18

Two equation becomes

9x - 6y = 21

8x - 6y = 18

Subtracted 8x - 6y = 18 from 9x - 6y = 21 .

9x - 8x -6y + 6y = 21 - 18

x = 3

Put the  value of x in the equation 8x - 6y = 18 .

8 × 3 - 6y = 18

24 - 6y = 18

-6y = 18 - 24

-6y = - 6

$y = \frac{-6}{-6}$

y = 1

Therefore the solution of the equation 3x - 2y=7  , 4x - 3y=9 are (3,1 ) .
