Given the numerical equation:
11.5 - 3y = 48.5
Determine the value of y.
Solution:
In order to determine the value of y, we first transpose -3y and 48.5 to the opposite sides of the equation, hence it must be taken to note that in transposing a number, the sign changs.
11.5 - 3y = 48.5
11.5 - 48.5 = 3y
-37 = 3y
Divide both sides by 3 in order to determine the value of y.
-37/3 = 3y/3
y = -12.3333…
Final answer:
y = -12.3333…
