Question

Given that t+4=3u+8 find the value of t when u=3

Answer 1

Substitute u with 3 into the equation t + 4 = 3u + 8 and solve for t, resulting in t = 13.

Step-by-step explanation:

To find the value of t when u=3, we start with the given equation t + 4 = 3u + 8. We can substitute u with 3 and solve for t.

Here's the step-by-step solution:

1. Substitute u with 3 in the equation: t + 4 = 3(3) + 8.
2. Multiply 3 by 3: t + 4 = 9 + 8.
3. Add 9 and 8: t + 4 = 17.
4. Subtract 4 from both sides: t = 17 - 4.
5. Complete the calculation: t = 13.

Therefore, the value of t when u=3 is 13.
