Answer 3

Solving the Equation 4t + 7t + 21 = 120t

To solve the equation 4t + 7t + 21 = 120t, we can start by combining like terms on the left side of the equation.

Step 1: Combine Like Terms 4t + 7t can be combined to 11t. So, the equation becomes: 11t + 21 = 120t

Step 2: Move the Variable Terms to One Side To solve for t, we need to move all the terms with t to one side of the equation. We can do this by subtracting 11t from both sides of the equation.

11t - 11t + 21 = 120t - 11t 21 = 109t

Step 3: Solve for t Now, to solve for t, we can divide both sides of the equation by 109.

t = 21 / 109 t ≈ 0.1927

So, the solution to the equation 4t + 7t + 21 = 120t is approximately t ≈ 0.1927.
