Answer:

x=12, y=14

Step-by-step explanation:

2x - y = 10

Solve the equation for y. Subtract 2x from both sides

- y = -2x+10

Divide both sides by -1

y=2x-10

Substitute 2x-10 for y in the second equation

3x - 2(2x-10)= 8

3x - 4x+20= 8

-1x+20= 8

Subtract 20 from both sides

-1x= -12

Divide both sides by -1

x= 12

y=2x-10

Substitute 12 for x

y=2(12)-10=14

y=14

2x-y=10
3x-2y=8

-y= -2x +10 multiply by(-1)
y=2x-10

3x-2(2x-10)=8
3x-4x+20=8
-x=-12 multply by (-1)
x=12
24-y =10
-y=-14
(12,14)

Find the absolute value of 1 and - 1
AlekseyPX
The absolute value of BOTH of those numbers is ' 1 '.

==========================================

Oh !  Wait just a second.  Did you mean for the  1  and the  -1  to be combined
in some way  ?  If that's what you had in mind,  then you'll have to be more
specific.   "And" is no mathematical operation that I know of.
