8t+4(t-1)=12-(8-3t)+1

解答

8 t + 4 (t - 1) = 12 - (8 - 3 t) + 1

解答

t = 1

求解步骤

8 t + 4 (t - 1) = 12 - (8 - 3 t) + 1

乘开

4 (t - 1) : 4 t - 4

8 t + 4 t - 4 = 12 - (8 - 3 t) + 1

同类项相加:

8 t + 4 t = 12 t

12 t - 4 = 12 - (8 - 3 t) + 1

展开

12 - (8 - 3 t) + 1 : 3 t + 5

12 t - 4 = 3 t + 5

将

4

到右边

12 t = 3 t + 9

将

3 t

(y-1)/4-(y-3)/5 =(1-2y)/(20)

\frac{y - 1}{4} - \frac{y - 3}{5} = \frac{1 - 2 y}{20}
