Answer:

Step-by-step explanation:
Given
q =
+ s ( subtract s from both sides )
q - s = ![\frac{p}{r}](https://tex.z-dn.net/?f=%5Cfrac%7Bp%7D%7Br%7D)
Multiply both sides by r
r(q - s) = p
Answer:
Y= 3x
Step-by-step explanation:
Answer:
first = 65
second = 325
Third = 165
Step-by-step explanation:
Let the first number = x
first: x
second: 5x
Third = x + 100
first + second + third = 555
x + 5x + x + 100 = 555 Combine
7x + 100 = 555 Subtract 100 from both sides
7x + 100 - 100 = 555 - 100
7x = 455 Divide by 7
7x/7 = 455/7
x = 65
7 (x-3) + 3(4-x) = -8
7x - 21 + 11 - 3x = -8
4x -10 = -8
4x = -18
X = -18/4
X = -4.5
