The two algebraic fractions can be added or subtracted only if they have the common denominators. So when adding or subtracting algebraic fractions the first thing that must be done is to take the LCM of the denominators and convert the denominators to same expressions. Only after this step the fractions can be added or subtracted. If this step is not performed, the operations cannot be performed correctly. This concept is similar to the addition and subtraction of simple fractions.

Solve: <br> x+y=5<br> x-4y=20
WARRIOR [948]

Answer:

x=8

y=-3

Step-by-step explanation:

let

x+y=5........ equation 1

x-4y=20....... equation 2

x=20+4y

substituting the value of x in eq 1

x+y=5

20+4y+y=5

5y=5-20

y=-15/5

y=-3

again putting the value of y in eq 2

x=20+4y

x=20+4(-3)

x=20-12

x=8

Find the 50th term of the following<br> arithmetic sequence 5, 9, 13, 17?
yarga [219]

Answer:

201

Step-by-step explanation:

First you need to know the position to term rule and to find this you use a formula which is:

tn = an + b

Where tn is the term number,  a is the difference between the other terms.

So the tposition to term rule here is 4n+1.

Then we substitute n for the value 50 making it 4(50) + 1 = 201.

201 is the 50th term
