Question 257488
The two equations are:
(i) {{{(3/7)x+(5/9)y=27}}}
(ii) {{{(1/9)x+(2/7)y=7}}}
multiply both equations by 63 to get
(iii) {{{(27)x+(35)y=1701}}}
(iv) {{{(7)x+(18)y=441}}}
multiply (iii) by 7 and (iv) by -27 to get
(v) {{{(189)x+(245)y=11907}}}
(vi) {{{(-189)x+(-486)y=-11907}}}
adding down, we get
{{{-241y = 0}}}
y = 0.
x = 63
{63,0)
