|p + 2| = 10;
p + 2 = 10;
p = 10 - 2;
p = 8;
-(p + 2) = 10;
-p - 2 = 10;
-p = 10 + 2;
-p = 12;
p = -12;
|8 + 2| = 10;
10 = 10;
|-12 + 2| = 10;
10 = 10

3x + 1 = 2x + 12

Weegy: 5x. User: x + 8 = 6 Weegy: so x=6-8=-2. User: 9x -3.2 = 6.8 + 8x Weegy: x=6.8+3.2=10 User: 5x = 7.3 + 4x Weegy: x=7.3 (More)

4 - 7x + 10 = 15 - 6x - 8

Weegy: 4-7x+10=15-6x-8 4+10=14 and 15-8=7 so now you have... 14-7x=7-6x - - - - - - - - - - - - - - - - - - - ? 7x+7x 14=7+x now use opposites to get -x= -7 which equals x=7 is your answer. User: 7 + x + 2 = 9 + 3 Weegy: 9+x=12.Hence x=12-9=3 (More)
