Question

solve the following equations ​

Answer 1

Answer:

3(t-3) = 12(3t-6)

3t-9 = 36t-72

3t-36t = -72+9

-33t = -63

t = -63/-33

=21/11

3x+4 = 5(x-4)

3x+4 = 5x -20

3x-5x = -20-4

-2x = -24

x = 12

7x-5 = 3x

7x-3x = 5

4x = 5

x = 5/4

7p-8 = 2p-6

7p-2p = -6+8

5p = 2

p = 2/5

Answer 2

Step-by-step explanation:

1) 3t-9=36t-72

-9+72=36t-3t

63=33t

t=21/11

2) 3x+4=5x-20

4+20=5x-3x

24=2x

x=12

3)7x-5=3x

7x-3x-5

4x=5

x=5/4

4)7p-8=2p-6

7p-2p=-6+8

5p=2

p=2/5
