<span>When we remove those parentheses, the sign of every term
within the parentheses changes.</span>

Problem 2.   Remove the parentheses.

a)   p + (q −r + s) <span>= p + q − r + s</span>

b)   p − (q −r + s) <span>= p − q + r − s</span>

In each of the following problems, remove the parentheses, then simplify
by adding the numbers.

For example,

<span><span><span>(x − 3) − (y − 4)</span>  =  <span>x − 3 − y + 4</span></span> <span>   =  <span>x − y + 1.</span></span></span>

The sign preceding  (x − 3)  is understood to be + . Therefore the signs within those parentheses do not change.

But the sign preceding (y − 4) is minus.  Therefore, y changes to −y, and −4 changes to +4.

Finally, it is the style in algebra to to write the literal terms, x − y, to the left of the numerical term.

Y varies directly with x and y = 12 when x =5 what is the value of y when x = 8
torisob [31]
Y and x are directly proportional, as stated by hypothesis. Let's use the rule of three to find y when x = 8.

x=5 --> y=12
x=8 --> y=?

? = (8*12)/5 = 96/5 = 19.2

So y directly varies with x, and y=12 when x = 5, then y=19.2 when x=8.

Hope this Helps! :D
