Question

7x+10y=4 find the linear equation​

Answer 1

Answer:

ANSWER

Rewriting the given equations, we get

7x−10y=4                              ...(i)

12x+18y=1                           ...(ii)

On multiplying (i) by 12 and (ii) by 7 and subtracting, we get

84x−120y=48

−84x−+126y=−7

             −246y=41

∴y=246−41

On putting y=246−41 in (i), we get

7x−10×246−41=4⇒x=24682           

Now, 4x+6y=4×24682+6×246−41=24682=31 and

8y−x=8×246−41−24682=246−810=
