2y=0.54
y=0.54/2
y=0.27 pencils
y+0.15=x
0.27+0.15=x
0x=0.42 pen
150 pencils x0.27=40.5$
225 pens x 0.42=94.5$

The sum of two numbers is 48.<br>the second number is seven times the first number​
dusya [7]

Answer:

\huge\boxed{\sf x =6,\ y = 42}

Step-by-step explanation:

Let the numbers be x and y

<h3>Given condition:</h3>

x + y = 48 --------(1)

y = 7x -------------(2)

Put Eq. (2) in (1)

x + 7x = 48

8x = 48

Divide 8 to both sides

x = 48/8

<h3>x = 6</h3>

Put x = 6 in Eq. (2)

y = 7 (6)

<h3>y = 42</h3>

\rule[225]{225}{2}
