In the attachment is the question
5(y-4) =3(y+2) open brackets and multiply 5y-20 = 3y +6 now just find the value of y.. can you?
Ummm
is it 3.25
nop.. can you put steps so i can tell where u made mistake.,
i jsut did the other you gave me
jsut added the like terms
added the 20 on both sides
divided it
gave me 3.5
divided by?
26
noo.. let me explain 5y-20=3y+6 first add 20 on both sides.
26
5y = 3y +26
ok
now subtract -3y on both sides.
2y
yes so 2y = 26 now divide both sides by 2
oh 13
