Question

solve by elimination method .
3x-5y-4=0
9x-2y-7 =0​

Answer 1

Answer:

There are two equations provided here.

3x – 5y – 4 = 0 or 3x -5y = 4 ……. (1).

9x = 2y + 7 or 9x -2y = 7 ……(2).

Answer 2

Step-by-step explanation:

Solving for y

3x-5y-4=0

9x-2y-7 =0

Multiply the 1st row by 3

9x -15y = 12

9x-2y-7 =0

Subtract the 2nd row from the 1st row.

- 13y = 5

y = - 5/13

Solving for x

9x −15 × - 5/13 = 12

x = 9/13
