Question

X/7+y=-11/7 ...1
X-5y/3=2 ...2

Answer 1

see your first equation will be x+7y = -11 and second will be 3x-5y=6 
and by multiplying 3 in eqn.1 nad subtracting from 2 y=-3/2 and then x =-1/2

Answer 2

In equation 1 x/7+11/7=-y =&x+11=-7y =& x=-7y-11......3 In eq 2 x-5y/3=2 3x-5y=6 x=(6+5y)/3....4 Now from eq 3&4 -11-7y=(6+5y)/3 -33-21y=6+5y 26y=-39 y=-39/26 =-3/2 Substitute value of y in eq 4 x=(6+5×-3/2)/3. {Take -3/2 as -1.5) =(6-7.5)/3 =-1.5/3 =-1/2
