Answer:
x=6 & y=5
Step-by-step explanation:
10x + 3y= 75........1
6x-5y= 11.............2
multiply 5 in eqn 1 and multiply by 3 in eqn 2,
we get new eqn from eqn 1,
50x +15y =375.....3
and
18x -15y=33.........4
by solving that eqns we get,
add eqn 3 and 4,
50x +15y =375
+
18x -15y=33
= 68x =408
so x=6
put x=6 in eqn 2,
6x -5y=11
36-5y=11
so y= 5
Therefore x=6 and y=5
Hope helped.....
