The equation is equivalent to:$$3(t-7) + 12 = 12$$$$3t - 21 + 12 = 12$$$$3t = 21$$$$t = 7$$So the only solution is t = 7, which is not one of the choices. However, the equation is undefined at t = 7, so the correct answer is -1.

Solve the Equation 3+12t−7=12t(t−7)3 + \frac { 12 } { t - 7 } = \frac { 12 } { t ( t - 7 ) }3+t−712​=t(t−7)12​

Solve the Equation $3 + \frac { 12 } { t - 7 } = \frac { 12 } { t ( t - 7 ) }$
