✔ 最佳答案
3t = 10
t = 10 / 3
t = 3 ⅓
3t + 20 = 30
3t = 10
t = 10/3
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
