Question

x-3y-3=0 3x-9y-2=0 elimination method​

Answer 1

Answer:

(x-3y-3=0)3

3x-9y-2=0

so,3x-9y-9=0

3x-9y-2=0

now you can solve

Answer 2

The given system of equations has no solution

Solution:

Given equations are:

x - 3y - 3 = 0

3x - 9y - 2 = 0

Rewrite

x - 3y = 3 ---- eqn 1

3x - 9y = 2 -------- eqn 2

We have to solve by elimination method

Multiply eqn 1 by -3

-3x + 9y = -9 ----- eqn 3

Add eqn 2 and eqn 3

3x - 9y = 2

-3x + 9y = -9

( + ) -------------

0 = 2 - 9

$0 \neq -7$

Thus the given system of equations has no solution
