- 3w = -36
Divide each side by -3 :
w = 12
If: 3w = 42 Then: w = 14
Well 3 times twelve is 36 36-3w equals 33w 33w time twelve 396w all you need to worry about though is 3 times twelve which is 36 :)
12
-13
This is an example of the "commutative" property.

If: 3w = 42 Then: w = 14

3w -6 = -15 3w = -15+6 3w = -9 w = -3
If: 3w-17 = 4 Then: w = 7
Well 3 times twelve is 36 36-3w equals 33w 33w time twelve 396w all you need to worry about though is 3 times twelve which is 36 :)
3w + 4 = 24 .......- 4... - 4 .......3w = 20 .......÷3 ...÷3 .........w = 20/3 or 6.6667

3w - 2 = 2w + 3 Add 2 to both sides: 3w = 2w + 5 Subtract 2w from both sides: w = 5
