#t = 6#

Question:

#−9t+18=4t−60#

Answer:

Move the #t#s to one side

#18=4t−60+9t#

Move the like numerals to one side (opposite side to which the #t# is on)

#60+18=4t+9t#

Add like terms

#78=13t#

To get #t# on its own, divide both sides by #13# (what you do on one side must be done on the other)

#78/13 = (13t)/13#

#78/13=t#

Solve the division

#78/13 = 6#

Therefore,

#6 = t#
