Question 197661
3x-4y=10
x=6y-1
now replace x in the first equation with(6y-1) & solve for y.
3(6y-1)-4y=10
18y-3-4y=10
14y=10+3
14y=13
y=13/14 ans.
x=6*13/14-1
x=78/14-1
x=(78-1*14)/14
x=(78-14)/14
x=64/14
x=32/7 ans.
Proof:
3*32/7-4*13/14=10
96/7-52/14=10
(96*2-52)/14=10
(192-52)/14=10
140/14=10
10=10
