y = -2

Step-by-step explanation:

10y-(4y+8)= -20

Open the bracket:

10y - 4y - 8 = -20

Note: multiplication of opposite signs give a negative number

Collect like terms:

10y - 4y = -20 + 8

6y = -12

Divide through by 6:


\begin{gathered} (6y)/(6)=(-12)/(6) \\ y\text{ = -2} \end{gathered}

The answer is y = -2
