Pre-Algebra Help please.......?

Question

1. 8-t over 2=53
2. 75=m over 3 +10
3. 3 over 5 p+18=24
4. 0.05x-0.08+x=0.97
5. 2.5y+3.5=-1.5
6. 6.3p+1.2p=22.5

Answer 1

1. t=-98
2. m=975
3. p=-143/40
4. x=1
5. y=-2
6. p=3

Answer 2

1. Multiply both sides by 2 which gives you:
8-t=106
Subtract 8 from both sides which gives you:
-t=98
so t=-98

2. 75=m over 13 (add 3+10)
Multiply both sides by 13 which gives you:
975 = m

3. Figure that one out yourself...I'm stumped.

4. add 0.05x + 1x that gives you:
1.05x - 0.08 = 0.97
add 0.08 to both sides which gives you:
1.05x = 1.05
so x = 1 (divide both sides by 1.05)

5. Subtract 3.5 from both sides which gives you:
2.5y = -5
Divide both sides by 2.5
y = -2

6. p=3
(add 6.3p + 1.2p which gives you 7.5p, then divide both sides by 7.5. 22.5/7.5 = 3)

Answer 3

1: 13.25
2: 975
3: -2
4: 1
5: -2
6: 3
