Hey there! :)
3/2 + t = 1/2
To solve for t, we must isolate our given variable [f].
So, we must first subtract 3/2 from both sides.
3/2 + t - 3/2 = 1/2 - 3/2
Simplify.
t = -2/2
Simplify.
t = -1
Therefore, our variable [f] equals -1.
To check as to whether or not t is truly equal to -1, we must plug in -1 for t into our original equation.
3/2 + t = 1/2
3/2 + (-1) = 1/2
3/2 + (-2/2) = 1/2
Simplify.
1/2 = 1/2
Therefore, f = -1
~Hope I helped!~
