Question

solve : 4x - 18 = 3y​

Answer 1

Answer:

4x-3y=18.......(i)

6x+7y=4........(ii)

so multiply (i) equation by 6 and (ii) equation by 4

then 24x-18y=108......(iii)

24x+28y=16........(iv)

subtract (iii)and(iv)

24x-18y=108

24x+28y=16

+. - -

..........................

o-46y=92

-y=92/46

y=-2

so put y in equation (i)

4x-3y=18

4x-3(-2)=18

4x+6=18

4x=18-6

4x=12

x=12/4

x=3
