The correct Answer is:
To solve the equation \( t - (2t + 5) - 5(1 - 2t) = 2(3 + 4t) - 3(t - 4) \), we will follow these steps: ### Step 1: Expand the equation Start by expanding both sides of the equation. Left-hand side: \[ t - (2t + 5) - 5(1 - 2t) \] Distributing the negative sign and the multiplication: \[ = t - 2t - 5 - 5 + 10t \] Combine like terms: \[ = (t - 2t + 10t) + (-5 - 5) = 9t - 10 \] Right-hand side: \[ 2(3 + 4t) - 3(t - 4) \] Distributing: \[ = 6 + 8t - 3t + 12 \] Combine like terms: \[ = (8t - 3t) + (6 + 12) = 5t + 18 \] Now the equation is: \[ 9t - 10 = 5t + 18 \] ### Step 2: Move all terms involving \( t \) to one side Subtract \( 5t \) from both sides: \[ 9t - 5t - 10 = 18 \] This simplifies to: \[ 4t - 10 = 18 \] ### Step 3: Move constant terms to the other side Add \( 10 \) to both sides: \[ 4t = 18 + 10 \] This simplifies to: \[ 4t = 28 \] ### Step 4: Solve for \( t \) Divide both sides by \( 4 \): \[ t = \frac{28}{4} \] This simplifies to: \[ t = 7 \] ### Step 5: Check the solution Substitute \( t = 7 \) back into the original equation to verify: Left-hand side: \[ 7 - (2(7) + 5) - 5(1 - 2(7)) = 7 - (14 + 5) - 5(1 - 14) = 7 - 19 - 5(-13) \] Calculating: \[ = 7 - 19 + 65 = 53 \] Right-hand side: \[ 2(3 + 4(7)) - 3(7 - 4) = 2(3 + 28) - 3(3) = 2(31) - 9 = 62 - 9 = 53 \] Both sides are equal, so the solution is verified. ### Final Answer: \[ t = 7 \]
