Determine the equivalent system for the given system of equations.<br> 4x - 5y = 2<br> 3x - y = 8
Black_prince [1.1K]

Solving the system of equations we get solution set (38/11,26/11)

Step-by-step explanation:

We need to solve the system of equations:

4x - 5y = 2\\3x - y = 8

Let:

4x - 5y = 2\,\,\,eq(1)\\3x - y = 8\,\,\,eq(2)

Multiply equation 2 with 5 and subtract both equations to find value of x:

4x - 5y = 2\\15x - 5y = 40\\-\,\,\,\,+\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,-\\--------\\-11x=-38\\x=\frac{-38}{-11}\\x=\frac{38}{11}

So, value of x = 38/11

Now, finding y:

Putting value of x in equation 2

3x-y=8\\3(\frac{38}{11})-y=8\\\frac{114}{11}-y=8\\-y=8-\frac{114}{11}\\-y=\frac{8*11-114}{11}\\-y=\frac{88-114}{11}\\-y=\frac{-26}{11}\\y=\frac{26}{11}

So, value of y = 26/11

So, Solving the system of equations we get solution set (38/11,26/11)

The length of a yearbook is 10 inches. The top margin is 1/2 inches and the bottom margin is 3/4 inch. What is the length of the
Lyrx [107]

Answer:

The length of the page inside the margins=8 3/4 inches

Step-by-step explanation:

The total length of the year book can be expressed as;

L=l1+l2+l3

where;

L=Total length of yearbook

l1=top margin length

l2=inside margin length

l3=bottom margin length

In our case;

L=10 inches

l1=1/2 inches

l2=unknown

l3=3/4 inches

replacing;

10=(1/2)+l2+(3/4)

(1/2)+(3/4)+l2=10

(5/4)+l2=10

l2=(10)-(5/4)

l2=8 3/4 inches

The length of the page inside the margins=8 3/4 inches
