Question

-10(Y-1)=-3Y-11?

Answer 1

You may distribute.

\( \color{Black}{\Rightarrow -10y + 10 = -3y - 11 }\)

Add 11 to both sides.

\( \color{Black}{\Rightarrow -10y + 21 = -3y }\)

Add 10y to both sides.

\( \color{Black}{\Rightarrow 7y = 21 }\)

Divide both sides by 7.
\( \color{Black}{\Rightarrow y = 3}\)

Answer 2

You can do that way^^ or
Distribute
10y + 10 = -3y -11
subtract 10 to the other side
-10y = -3y -21
and 3y to the other side
-7y = -21
Divide by -7
y=3 :)
