4y=3x-1

A.4y=4x-1
B.y=4x+3
C.2y=x-3
D.y=4x-4

Answer 1

probably easiest to isolate \(y\) in the first equation because that only takes one step
\[4x=y+4\iff y=4x-4\]

Answer 2

thanks again!

Answer 3

can you help me with this one?choose a variablbe to isolate and what it is equal to in the system of equations below.
16x=2y+18
4y=3x-1
A.y=8x-9
B.x=-8y+9
C.y=8x+9
D.y=x-9

Answer 8

now i have to think

Answer 9

oh it is A
\[16x=2y+18\]
\[16x-18=2y\]
\[8x-9=y\] or
\[y=8x-9\]

Answer 10

thank youu
