Question

Proper answer with explaination only...
SOLVE: 141x + 93y= 189; 93x + 141y =45

Answer 1

Answer:

there are two equations,

141x + 93y = 189 - (i)

93x + 141y = 45 - (ii)

so add eq. (i) & (ii)

Then we get = 234x + 234y = 234

234(x+y) = 234

x + y = 1

x = 1 - y - (iii)

put the value of x in eq.(i)

141(1-y) +93y =189

y =-1

put the value of y in eq.(iii)

x = 1 - (-1)

x = 1 + 1

x = 2

THEREFORE THE ANSWER IS

X= 2 , Y = -1
