Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{2z - 5y}}}}}

Step-by-step explanation:

\sf{ - ( - 2z + 5y)}

Distribute negative ( - ) sign through the parentheses

\sf{( - ) \times ( - 2z)  + ( - ) \times (5y)}

\dashrightarrow{ \sf{2z   + ( - 5y)}}

\dashrightarrow{ \sf{2z - 5y}}

Hope I helped!

3(x-1)=2x+9. Solve equation
Anna11 [10]

Hello.

In order to solve this equation, we need to isolate the variable (in this case, the variable is x)

The first step is to use the Distributive Property and distribute 3:

\mathrm{3(x-1)=2x+9}

\mathrm{3x-3=2x+9}

Now, add 3 to both sides:

\mathrm{3x-3+3=2x+9+3}

\mathrm{3x=2x+9+3}

\mathrm{3x=2x+12}

Now, subtract 2x from both sides:

\mathrm{3x-2x=2x-2x+12}\\\mathrm{3x-2x=12}

\mathrm{x=12}

Therefore, the answer is

\mathrm{x=12}

I hope it helps.

Have a nice day.
