-8t = -152 t = 19
8t = 36 t = 36/8 = 18/4 9/2 = 4.5
That's entirely correct.If you divide each side of the equation by 't',you reach the startling conclusion that 5 = 5 !
The "answer" is the number that can be put in place of 't' and makes [ 8t-3=9 ]a true statement.Here's how to find out what it is:8t - 3 = 9Add 3 to each side of the equation:8t = 12Divide each side by 8:t = 1.5
The expression 15-t plus 8t-13 simplifies to 7t + 2.
