First you change the number that is not with "p" and it changes with the opposite sign
-0.75p = 0.25 + 2
-0.75p = 2.25
then as -0.75 and p are multiplying, you pass -0.75 as dividing
p = 2.25/-0.75
p = 3
Required algebraic expression is 3/z
Answer: 
Step-by-step explanation:
Given
Function is 



from (i) and (ii) we get

X= mountain dew y= coke
-(5x+5y=1160)
8x+5y=1523
-5x-5y=-1160
+
8x+5y=1523
<u>3x</u>=<u>363
</u><u />3 3
x=121 g of sugar in Mt. Dew
8x+5y=1523 plug in 3 in x
24+5y-24= 1523-24
<u>5y</u>= <u>1499
</u>5 5
y= 299.8 grams of sugar in coke
