If 2 ( 3 t - 10 ) + t = 40 + 4 t , what is the value

Question

If 2 ( 3 t - 10 ) + t = 40 + 4 t , what is the value of 3 t ?

Accepted Answer

The correct answer is 60 . Subtracting t from both sides of the given equation yields 2 ( 3 t - 10 ) = 40 + 3 t . Applying the distributive property to the left-hand side of this equation yields 6 t - 20 = 40 + 3 t . Adding 20 to both sides of this equation yields 6 t = 60 + 3 t . Subtracting 3 t from both sides of this equation yields 3 t = 60 . Therefore, the value of 3 t is 60 .
