Answer:
x = -20
y = -62
Step-by-step explanation:
Suppose x and y two number and such that :
- their sum = -102
- and y is 62 less than x
Which means :
then
then
x + y = (y+62) + y = -102
then
2y + 62 = -102
then
2y = -164
then
y = -164/2 = -82
therefore
x = y + 62 = -82 + 62 = -20
To start you need to get rid of the denominator so you add -4 by 8 to get 4 then multiply both sides by 4 to remove the denominator giving you -8= 5-y1. After that subtract 5 from both sides giving you -13= -y1, dividing by -1 you then get y1= 13

Step-by-step explanation:
Step-by-step explanation:
The expression for he earning of Allison and her allowance is as follows :
15x+100y
Part A
Variables are x and y. Coefficients are 15 and 100.
Part (B)
There are two terms in this expression. + is used to separate the terms. 15x and 100y are the terms.
Part (C) As $15 shows her earning from allowances. Hence, 15x shows allowance.
