Question

Find the value of x and y in 228x + 171y = 399 and 171x + 228y = 399

Answer 1

Answer:

X=1,Y=1

Step-by-step explanation:

228X+171Y=399 eq1

171X+228Y=399 eq2

Multiply eq1 by 171 and eq2 by 228

38988X+29241Y=68229 eq1

38988X+51984Y=90972 eq2

Subtract eq2 from eq1

38988X+29241Y=68229

38988X+51984Y=90972

- 22743Y= - 22743

Y=-22743/-22743

Y=1

PUT THE VALUE OF Y IN EQ2

171X+228Y=399

171X+228=399

171X=399-228

171X=171

X=171/171

X=1
