Solve using the addition method 8x-10y-2 7x-5y=13?

Answer 1

Addition method? I assume you mean the normal way to solve them. You won't get a single answer.

First, gather like terms
(8x - 2.7x) +(-10y - 5y) = 13
do the arithmetic
5.3x - 15y = 13
That is as far as you can go to solve it. You can put values in for x and calculate values for y or do the same with y.
Have fun.

Or are these two simultaneous equations? word your questions better and set them out better if you want correct answers to the questions you ask.

How parochial can you get? Summer? Not here! Can't wait till it arrives, though.

Answer 2

7x-5y=13
14x-10y=26------ 1
Add 1 into 8x-10y=2
8x-10y+14x+10y=2+26
22x=28
x=11/14
Sub this back into 1
11-10y=26
y=-1 1/2

Answer 3

8x-10y=2
7x-5y=13

mulitply the bottom equation by -2

8x-10y=2
-14x+10y= -26
----------------------
add the equations going down
-6x=-24
x=4

8(4)-10y=2
32-10y=2
-10y=2-32

y=3

Answer 4

8x-10y=2
7x-5y=13
_________ multiplying the bottom by -2

8x-10y = 2
-14x+10y = -23
--------------------
equals --> 6x=-21 therefore x = -21/6 and substituting in ...y=2.3

Answer 5

7(8x-10y-2) ==>56x-70y-14
8(7x-5y+=13)==>56x-40y=104
--------------------
120y-14=104
+14 =+14
120y=118

Answer 6

Hey Angelica, it's summertime. Why not get some fresh air and enjoy your life. Solving this problem will lead to a grade, which leads to a diploma, which leads to a job, which leads to you waking up one day wondering what the hell happened to your life.
