no answer to t
5t - 5 = 5t +7 ( subtract 5t from both sides reducing to)
-5 = +7
Negative 5 does not equal positive 7.
You don't for t, as gathering your coefficient variables together = 0 5t - 5 = 5t + 7 now, subtracting 5t from either side to get the variables on one side of the equation renders this. - 5 does not = 7
3t - 1
7 +5t
7s + 4t
5t - 9 = 26(Add 9 to both sides)5t = 35(Divide both sides by 5)t = 7
The idea is to get the t on it's own. Whatever you do to one side you do to the other. So first you minus the 7 so you get 5t = 20 the you divide by 5 to leave t on it's own so t = 4
5t - 7 = 11 5t - 7 + 7 = 11 + 7 5t = 18 5t/5 = 18/5 t = 18/5 t = 3 3/5
-5t + 9 + 2t = 30Combine like terms on the left side:-3t + 9 = 30Multiply both sides by -1"3t - 9 = -30Add 9 to both sides:3t = -21Divide both sides by 3:t = -7
It equals 24.

It doesn't ! -7 plus -5 equals -12 ! -7 plus 5 equals -2
