Question

Solve the following pair of simultaneous equations. 8x-3y=16 , 6x-7y=31 .​

Answer 1

Step-by-step explanation:

firs multiple by 6 in eq first and by 8 in equation second

so we get

48x-18y=96

48x-56y=248

no change the sign in equation second

so 48x will cancel out

36y=-152

y= -152/36

now put the value of y in euqal 48x-18y=96

48x-18×-152/36=96

48x -76=96

x=96+76/48

x= 172/48

thesea re the answers for full answer you can solve the values

i hope you'll find it helpful ❤️
