Question

solve the following simultaneous equations​

Answer 1

Step-by-step explanation:

49x = 172 + 57y

x = (172 + 57y)/49 eq.(i)

57x = 252 + 49y

x = (252 + 49y)/57 eq.(ii)

(172 + 57y)/49 = (252 + 49y)/57

172*57 + 57*57y = 252*49 + 49*49y

3249y - 2401y = 12348 - 9804

848y = 2544

y = 3

Substitute value of in any of equation

Let put it in eq.(i)

x = (172 + 57*3)/49

x = (172 + 171)/49

x = 343/49

x = 7
