Answer:
1. t=10
2. t=4
3. t=40
Explanation:
Isolate the term of t from one side of the equation.
1. 4t=40
First, you have to divide by 4 from both sides.
4t/4=40/4
Solve.
Divide the numbers from left to right.
40/4=10
t=10
2. 10+t=14
First, change sides.
t+10=14
Then, subtract by 10 from both sides.
t+10-10=14-10
Solve.
Subtract the numbers from left to right.
14-10=4
t=4
3. 70-t=30
First, subtract by 70 from both sides.
70-t-70=30-70
Solve.
30-70=-40
Rewrite the problem down.
-t=-40
Divide by -1 from both sides.
-t/-1=-40/-1
Solve.
Divide the numbers from left to right.
-40/-1=40
t=40
- Therefore, the correct answer is t=10, t=4, and t=40.
