Question

sove by using elimination method 6x-2y=-9 and 3x-y=-12​

Answer 1

Answer:

6x-2y = -9...... (1)

3x-y = -12...... (2)

Multiplying the eq(2) by 2

6x-2y = -24....... (3)

now, subtracting the eq 1 and 3

6x-2y = - 9

6x-2y=-12

= 3

something is error in this question because both x and y is cancel
