2x + 2y = 20 using the simultaneous method 2x  2y = 4 ____________ 4x = 24 ( divide by four) x = 6 substitute x in one of the two equations 2x + 2y = 20 2 (6) + 2y = 20 12 +2y = 20 2y = 20  12 2y = 8 (divide by 2) y = 4 Answer : X = 6 , Y = 4

First, get the least common denominator. 5 and 10 are your denominators, since 5 is a multiple of 10, then 10 becomes your common denominator because you can divide 10 by 5 and the digit itself (10).
____________
10
We'll treat 7/5 as first term and 13/10 as the second term. Get the quotient from each term by dividing the greatest common denominator (10) by the denominator of both terms.
a. 10/5 = 2
b. 10/10 = 1
Multiply the first quotient with the numerator of the first term and do the same with second quotient with the numerator of the second term, include the numeric sign (positive/negative)
a. 2 * (7)
b. 1 * (13)
2(7) + 1(13)

10
Perform operation.
14  13

10
The answer will be 27/10

To subtract (or add) fractions, you need to have a common denominator. That means the numbers on the bottom have to be the same. Since the first fraction (7/5) is in 5ths, you have to convert it to 10ths. You do this by multiplying by (2/2), since (2/2) is equal to 1, and multiplying any number by 1 gives you the same number. So...
7/5 x 2/2
=
(7 x 2) / (5 x 2)
I'll let you figure out the rest

Multiply both to make the denominator 50,
7/5 x 10 = 70/50
13/10 x 5 = 65/50
70  65 = 135
135/50
then simplify

You want the denominators (number on the bottom of a fraction) the same.
To do this, multiply 7/5 by 2
ie
2 * (7/5) = 14/10
Which makes it
14/10  13/10
then it's just 1413 and make the answer over 10
ie
14  13 = 27 / 10
Answer 27 / 10

and just put it in your calculator
negative 7:5 minus 13 :10.
or do those individually, cause maybe the fraction will minimizxe and give you a decent answer not " 2.333333"

Find your lowest common denominator (LCD)
In this case, it's 10
So 7/5 is the same as 14/10 (multiply top and bottom by 2)
So your expression becomes
14/1013/10
=27/10

Both must have a common demoinator, which is 10;
so rename 7/5 to 14\10 then work problem:
14\10  13\10 = 27/10
Now convert to mixed number by dividing 27 by 10
you get :  2 and 7/10 th's or 2.7

7/5  13/10 (convert to the least common denominator of 5 and 10, which is 10; 5 goes into 10 two times, so multiply 7/5 by 2/2)
7/5*2/2  13/10

Never think you are dumb, you just have not been taught the information correctly. Try looking at your textbook before coming here for help, or go to your teacher for further help.
But anyways:
7/5  13/10
Make sure you make the denominator the same
multiply the first numbers numerator and denominator by 2
so you have 7/5=  14/10
so 14/1013/10
keep the denominator the same and solve: 1413
14/1013/10 27/10 or 2 7/10 or 2.7
