Solve the following equation: *<br> -9 (t – 2) = 4(t – 15)
iragen [17]

Answer:

6 =t

Step-by-step explanation:

-9 (t – 2) = 4(t – 15)

Distribute

-9t +18 = 4t -60

Add 9t to each side

-9t +18+9t  = 4t+9t -60

18 = 13t -60

Add 60 to each side

18+60 = 13t-60+60

78 = 13t

Divide each side by 13

78/13 = 13t/13

6 =t
