Question

solve the equations:
-5y-9=-(y-1)

3y+20=3+2y

Answer 1

Are you asking two questions?

For first equation, distribute -1 on right side.

You should have \(-5y-9 = -y+1\)

Now add both sides by y: \(-5y-9 \color{red}{+y}= -y+1\color{red}{+y}\)
\(-4y-9 = \cancel{-y}+1+\cancel{y}\)
\(-4y-9 = 1\)

See how I approach this problem? Can you do the rest?

Answer 2

Yes two different questions
