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.

I hope this helps! Let me know if you have any questions.
