1. solve -a/-6+5 =2
2. 5(12-3p)=15p+60
3. 3(y-2) = 6(y-1) - 3y
4. 3a+21 = 7-4a
5. what i the solution set | 2x-3| =7

1.) -a/-6+5 = 2
-a/-1 = 2
a = 2

2.) 5(12 - 3p) = 15p + 60
60 - 15p = 15p + 60
30p = 0
p = 0

3.) 3(y - 2) = 6(y - 1) - 3y
3y - 6 = 6y - 6 - 3y
3y - 6 = 3y - 6
0 = 0

4.) 3a + 21 = 7 - 4a
3a + 4a = 7 - 21
7a = -14
a = -14/7 = -2
a = -2

|2x - 3| = 7
2x - 3 = 7 or 2x - 3 = -7
2x = 7 + 3 or 2x = -7 + 3
2x = 10 or 2x = -4
x = 10/2 or x = -4/2
x = 5 or x = -2
