Use Transposition method to simplify the given equation: (You can bring terms to the left or to the right but changing their signs)

3t + 20 = 30

3t = 30 - 20

3t = 10

t = 10/3 ----------->>> ans

3t+20=30
3t=10
t=10/3
t=3.33333333333333333333333333333333333333........33333333

Subtract 20 from both sides

3t + 20 - 20 = 30 - 20

3t = 10

Divide both sides by 3 to get

3y/3 = 10/3

or y = 10/3

Answer:

3t + 20 = 30
3t = 30-20
3t = 10
t = 10/3 OR 10÷3
t = 3 1/3

3t+20=30
=>3t=30-20
=>3t=10
=>t=10/3

3t + 20 = 30
3t = 30 - 20
3t = 10
t = 10/3
t = 3 1/3
