Question

Solve for t.
3(t – 13) = 18

Answer 1

t = 19

Explanation:

1) Distribute the 3. Now the equation is 3t - 39 = 18

2) Add 39 to both sides. The equations is now 3t = 57

3) Divide both sides by 3. t = 19

4) Plug 19 in for t in the original equation to double check your work. 19 is correct.

Answer 2

t = 19

Explanation:

Step 1: Distribute

3(t - 13) = 18

3t - 39 = 18

Step 2: Add 39 to both sides

3t - 39 + 39 = 18 + 39

3t = 57

Step 3: Divide both sides by 3

3t / 3 = 57 / 3

t = 19

Answer: t = 19
