Question

-4l+5b=-140 ; 2l-10b=-80
Pls solve these equations

Answer 1

Hey!

-4L+ 5B= -140

So first subtract 5B from -140 which will leave you with -145, then divide it by -4 which leaves you with the answer of 36.25 negative

2L-10B=-80 same thing applies as above ;)

Answer 2

Hence,
l = 60 and b = 20
