solvefor t,r= e/(i^2)*t

解答

求解

t, r = \frac{e}{i ^{2}} \cdot t

t = - \frac{r}{e}

求解步骤

r = \frac{e}{i ^{2}} t

交换两边

\frac{e}{i ^{2}} t = r

化简

\frac{e}{i ^{2}} : - e

(- e) t = r

两边除以

- e

t = - \frac{r}{e}

so l v e f or x, 2 (x - 1) + 3 y = 4

(a - 2020) x + 2022 = b

12 - 2 i = 3 k - 2 i

k = \frac{( 2 f ( - 2 ) - 4 f ( f ( - 3 ) ) )}{( f ( - 1 ) - 3 )}

\frac{1}{( lo g _{6} ( 12 ) )} + \frac{1}{( lo g _{2} ( 12 ) )} = x
