Simplify. Combine like terms.
7 - 9 = -2
4t - 2 = -6 + 6t
Isolate the t. Note the equal sign. Add 2 to both sides, and subtract 6t from both sides
4t (-6t) - 2 (+2) = -6 (+2) + 6t (-6t)
4t - 6t = -6 + 2
Simplify
-2t = - 4
Isolate the t, divide - 2 from both sides
-2t/-2 = -4/-2
t = -4/-2
t = 2
t = 2 is your answer
hope this helps
