Question

Solve 2x+4y-10=0;3x+6y-12=0

Answer 1

Answer:

9

Step-by-step explanation:

let 2x+4y+10=0 be (I)

and 3x+6y-12=0 be (ii)

Then, subtract ii and I,

EQ.i. 2(x+2y+5)=0

EQ.ii. 3(x+2y-4)=0

Send 2 to zero then we will have eq.i. x+2y+5=0

EQ.ii. x+2y-4=0

so subtract eq.i. and eq.ii

Then we will have 9...
