Question

4y+4=5y-4 plz help me guys ​

Answer 1

Answer:

4y + 4 = 5y - 4

so ,

4+4 = 5y - 4y

8 = y

Therefore value of y is 8.

Answer 2

4y+4=5y-4

4y-5y=-4-4

-y=-8

- get cancelled in both l .h.s and r.h.s

so y=8

proof:

if y=8

4×8+4=5×8-4

l.h.s.=RHS { we need to prove it}

32+4=40-4

36=36

hence LHS=RHS

hence proved
