Question

5t+30-2t=42 решите пожалуйста

Answer 1

5t+30-2t=42
3t = 12
t = 4

Answer 2

Solving the Equation 5t + 30 - 2t = 42

To solve the equation 5t + 30 - 2t = 42, we can combine like terms and then solve for t.

Step 1: Combine Like Terms Combine the terms with t on one side of the equation and the constant terms on the other side.

5t - 2t + 30 = 42 (5t - 2t) + 30 = 42 3t + 30 = 42

Step 2: Solve for t Subtract 30 from both sides of the equation to isolate the term with t.

3t + 30 - 30 = 42 - 30 3t = 12

Finally, divide both sides by 3 to solve for t.

3t / 3 = 12 / 3 t = 4

Therefore, the solution to the equation 5t + 30 - 2t = 42 is t = 4.
