3w - 2 = 2w + 3 Add 2 to both sides: 3w = 2w + 5 Subtract 2w from both sides: w = 5
7w + 2 = 3w + 94 Subtract 3w from both sides: 4w + 2 = 94 Subtract 2 from both sides: 4w = 92 Divide both sides by 4: w = 23
20 = 400
2+2+2+10+5+5+5+20+20+20+20+20+20=151
Without an equality sign the given expression can't be considered to be an equation
This is an example of the "commutative" property.

5w+2 = 2w+5 5w-2w = 5-2 3w = 3 w = 1
20 = 400
3w^2 - 8w + 4 = (3w -2) (w-2) So 3w-2=0, then 3w=2, so w=2/3, w-2=0, so w=2. Your solutions are w=2/3 and w=2.
