Question

by elimination method : 5x - y = 136. x- 3y = 6​

Answer 1

Answer:

5x-y=136

x-3y=6

now subtract both equations

4x+ 4y=130

4(x+y)=130

now divide 130/4

so equation will be

x+y=130/4

so X+y=32.5 we take 33

x=30/y

now put in second equation

x-3y=6

33/y-3y=6

so cut both y

33-3=6

30=6so

30/6 = 5
