7t-21+t+4=15

7t-21+t+4=15

I did the last problem for you. Now it's your turn. What do you think the answer is?

i know 8t-21+4=15 but now idk what to do next

The next step is to get the known numbers on the other side of the equation.

8t-21+4=15
8t - 17 = 15
8t - 17 + 17 = 15 + 17
8t = 32
t = ?

To solve the equation 7t - 21 + t + 4 = 15, we need to combine like terms, isolate the variable t, and find its value.

Step 1: Combine like terms.
7t + t - 21 + 4 = 15
Combining the terms with 't' and the constant terms, we have:
8t - 17 = 15

Step 2: Move the constant term to the other side.
To isolate t, we need to move the constant term (-17) to the other side of the equation. We can do this by adding 17 to both sides of the equation:
8t - 17 + 17 = 15 + 17
8t = 32

Step 3: Solve for t.
To solve for t, we divide both sides of the equation by the coefficient of t, which is 8:
(8t) / 8 = 32 / 8
t = 4

Therefore, the solution to the equation 7t - 21 + t + 4 = 15 is t = 4.
