First, you would need to solve for t using the equation: 3t - 7 = 5t
Move all the numbers with variable on ones side
-7 = 5t - 3t
Combine like factors
-7 = 2t
Solve for t
-7/2 = t
After solving for t, you plug the answer into the equation you want to solve.
6 (-7/2) = -21
6*-7 = -42
-42/2 = -21
The answer is -21
