Question

7(y-2) - 4(5 - y) = 10​

Answer 1

Answer:

$7(y - 2) - 4(5 - y) \\ = 10$

$= > 7y - 14 - 20 + 4y = 10$

$= > 11y - 34 = 10 \\ \\ = > 11y = 44 \\ \\ = > y = 4$

$\huge\underline\bold {NOTE:}$

Adding and multiplying combinations of positive and negative integers can cause confusion.

So, always keep in mind that :

Two ‘pluses’ make a ‘plus’. Two ‘minus’ make a ‘minus’. And a plus and a minus make a minus.

Answer 2

Answer:

7(y-2) - 4(5-y) = 10

7y-14-20+4y = 10

11y = 10+14+20

11y = 44

y = 44/11

y = 4
