Question

2. 5 ( 3 – m) + 5m = 15






3. -2 |x| - 7 = -3

Answer 1

1.) 4-2y=2(9-y)
2y=2+(-18y)
2y=-16y
y=-8

Answer 2

no

Answer 3

2(9-y )= 18-2y by distributive property

Answer 4

Expand it out using the distributive property as zpup just did

5( 3 – m) + 5m = 15
(5*3)-(5*m)+(5m) = 15

Answer 5

The three equations are trick equations.

4 - 2 y = 2 (9 - y)
4 - 2 y = 18 - 2 y
4 != 18

5 (3 - m) + 5 m == 15
15 - 5 m + 5 m == 15
15 = 15

-7 - 2 Abs[x] == -3
Abs[x] != -2

Answer 6

Sorry. == is = in Mathematica. Did not edit the last two solutions.

Answer 7

Just so we're clear != == =/= || ≠:)

Answer 8

!= "not equal"
== "equal"

Answer 9

this was programming humor yes thank

Answer 10

@bibby

Ha Ha. Very clever. I happen to be a former programmer.

Answer 11

How do you solve number 3.

Answer 12

-7 - 2 Abs[x] = -3
- 2 Abs[x] = 7-3
- 2 Abs[x] = 4
Abs[x] = 4/(- 2)
Abs[x] ≠ -2
