solvefor y,r(t)=(t^2-2t)y+(3t+6)j

解答

求解

y, r (t) = (t^{2} - 2 t) y + (3 t + 6) j

解答

y = \frac{r t - j ( 3 t + 6 )}{t ^{2} - 2 t}; t \neq = 2, t \neq = 0

求解步骤

r (t) = (t^{2} - 2 t) y + (3 t + 6) j

交换两边

(t^{2} - 2 t) y + (3 t + 6) j = r t

(t^{2} - 2 t) y + (3 t + 6) j = r t

将

(3 t + 6) j

到右边

(t^{2} - 2 t) y = r t - (3 t + 6) j

两边除以

t^{2} - 2 t; t \neq = 2, t \neq = 0

y = \frac{r t - j ( 3 t + 6 )}{t ^{2} - 2 t}; t \neq = 2, t \neq = 0

solvefor z, p/(10)+z/3 =100

so l v e f or z, \frac{p}{10} + \frac{z}{3} = 100

h=sqrt(1/9)+sqrt(1/4)

h = \frac{1}{9} + \frac{1}{4}

y + 5 = 17, y

solvefor x,g= 3/4 f

so l v e f or x, g = \frac{3}{4} f

\frac{3 y + 2}{9} = \frac{4}{9}
