Sagot :
3x +y = 23 this is the same as y=23-3x
3x - 2y = 8 this is the same as 3x/2-8/2=y, which gives you; y=1,5x-4
so;y=23-3xy=1,5x-4
y=y
23-3x=1,5x-4
23+4=1,5x+3x
27=4,5x
27/4,5=x
x=6
the y is:
3*6+y=23
18+y=23
y=23-18
y=5
3x - 2y = 8 this is the same as 3x/2-8/2=y, which gives you; y=1,5x-4
so;y=23-3xy=1,5x-4
y=y
23-3x=1,5x-4
23+4=1,5x+3x
27=4,5x
27/4,5=x
x=6
the y is:
3*6+y=23
18+y=23
y=23-18
y=5
1) 3x +y=23 try to label them one and two.
2)3x -2y=8 First lets find the x. To do that we have to changed the y,and find the common number fo them.
---------------------------------
1) 3x+y=23 try to times the whole equation number 1) by 4, and equation 2) by 2.
2) 3x-2y=8
----------------------------------------------
1) 12x+4y=92 That's how the euation should look after you would times it.
2) 6x-4y=16 Then add them.
---------------------------------
12x +6x = 18x ..... 4y+4y_ this won't have to be solved at we only had to times it so we could eliminate does y's as we only wanted to find out x.
92+16=108
---------------------------------------------
So then we have...
18x = 108 This means we have to divide 108 by 18 to find out x.
108/18 = 6.
x=6.
-------------------------------------------------------------------------------------------------------------------
To find y we have to do the same method but we have to eliminate x, by findin a common number in x's.
1) 3x+y=23 Try to time the two equations by 2.
2)3x-2y=8
-----------------------------------------------
1) 6x+2y=46 Yoou should get something like that. Then add them.
2) 6x-4y=16
---------------------------------------------
6x+6x_ we won't gonna add them as we only had to multiply them to get the same answer to eliminate these.
2y+ -4y= -2y ............. 46+16=62
-------------------------------------------------------------------
So it should be: 2y=62
---------------------------------------------------------------
No we only have to divide 62 by 2, which is 31
so y=31.
