7(1 - y) = -3(y-2)<br> What is the answer
Fynjy0 [20]

Answer:

\huge y =  \frac{1}{4}

Step-by-step explanation:

7(1 - y) = -3(y-2)

<u>Expand the terms in the bracket</u>

That's

7 - 7y =  - 3y + 6

<u>Add 3y to both sides of the equation</u>

7 - 7y + 3y = 3y - 3y + 6 \\ 7 - 4y = 6

Subtract 7 from both sides by the equation

7 - 7  - 4y = 6 - 7 \\  - 4y =  - 1

<u>Divide both sides by - 4</u>

\frac{ - 4y}{ - 4}  =  \frac{ - 1}{ - 4}  \\

We have the final answer as

y =  \frac{1}{4}  \\

Hope this helps you
