Question

Solve -2 (t- 1) = 18

Answer 1

Answer:

t=-8

Step-by-step explanation:

-2 (t- 1) = 18

Divide each side by -2

-2 (t- 1)/-2 = 18/-2

t-1 = -9

Add 1 to each side

t-1+1 = -9+1

t = -8

Answer 2

Answer:

t = -8

Step-by-step explanation:

Isolate the variable, t. Note the equal sign, what you do to one side, you do to the other.

First, Divide -2 from both sides:

(-2(t - 1))/-2 = (18)/-2

t - 1 = 18/-2

t - 1 = -9

Isolate the variable t. Add 1 to both sides:

t - 1 (+1) = -9 (+1)

t = -9 + 1

t = -8

t = -8 is your answer.
