7 − 3 ( 5 t − 10 ) = 67
7 − ( 3 ∗ 5 t − 3 ∗ 10 ) = 67
7 − 15 t − ( − 30 ) = 67
7 − 15 t + 30 = 67
− 15 t = 67 − 30 − 7
− 15 t = 30
then...
t = − 15 30
t = − 2
Answer in an annex ....................................
The solution to the equation 7 − 3 ( 5 t − 10 ) = 67 is t = − 2 . This is found by simplifying and isolating the variable step by step. Lastly, dividing by -15 yields the final value for t.
