Answer:
The first step is to replace the y in y-x=15 with 7x (we can do this because the first equation tells us that they're equal)
solve and get
(2.5,17.5)
or x= 2.5 y=17.5
Step-by-step explanation:
The first step is to recognize that y=7x which means that we can just replace the y in the second equation with 7x
7x-x=15
6x=15
x=2.5
Then we can solve for y
y=7(2.5)
y=17.5

Answer:
7 1/8
Step-by-step explanation:
Convert the mixed fractions to normal fractions:
(9 * 4) + 2 = 38
(1 * 3) + 1 = 4
38/4 ÷ 4/3
Reduce it down as much as possible:
19/4 ÷ 4/3
Apply the fractions formula for division:
a / b ÷ c / d = a * d / b * c
19 * 3 / 2 * 4
57 / 8
Simplify:
7 1/8
