To get the variable by itself, which number needs to be moved?
To move the -5, you have to do the opposite operation. What operation will we use?
t = -12
-5(-12) = 60
2.5 = n
15 = 6(2.5)
2) Solve 15 = 6n

“Clear the fraction”
by multiplying both sides of the equation by the denominator.
4 ·· 4
x = -48
3 · = 18 · 3
2x = 54
x = 27
