Question

(t+9)20=140 what is t

Answer 1

-2

Explanation:

(t+9)20 = 140

Open the bracket first by multiplying everything by 20.

(20×t) + (20×9) = 140

20t + 180 = 140

20t + 180 - 180 = 140 - 180

20t = -40

20t/20 = -40/20

t = -2

Answer 2

t=-2

Explanation:

(t+9)20=140

Distribute the 20

20t +180 = 140

Subtract 180 from each side

20t +180-180 = 140-180

20t = -40

Divide by 20

20t/20 = -40/20

t=-2
