solvefor x,[(x+5)] 2/9-[(y+1)] 2/49 =1

解

解く

x, [(x + 5)] \frac{2}{9} - [(y + 1)] \frac{2}{49} = 1

解

x = \frac{- 31 + 18 y}{98}

解答ステップ

[(x + 5)] \frac{2}{9} - [(y + 1)] \frac{2}{49} = 1

[(y + 1)] \frac{2}{49}

を右側に移動します

[(x + 5)] \frac{2}{9} = \frac{51}{49} + \frac{2}{49} y

拡張

((x + 5)) \frac{2}{9} : \frac{2}{9} x + \frac{10}{9}

\frac{2}{9} x + \frac{10}{9} = \frac{51}{49} + \frac{2}{49} y

以下で両辺を乗じる:

9

2 x + 10 = \frac{459}{49} + \frac{18}{49} y

10

を右側に移動します

2 x = - \frac{31}{49} + \frac{18}{49} y

以下で両辺を割る

2

x = \frac{- 31 + 18 y}{98}

solvefor x,12x+4y=-12

so l v e f or x, 12 x + 4 y = - 12

solvefor x,5x-2y=1

so l v e f or x, 5 x - 2 y = 1

2/3 x-1/2-3/2 x=-2x

\frac{2}{3} x - \frac{1}{2} - \frac{3}{2} x = - 2 x

4/3 x+2/3 x= 1/3 x+5

\frac{4}{3} x + \frac{2}{3} x = \frac{1}{3} x + 5

4/9-2/9 s+1/9 s= 2/9-2/9 s

\frac{4}{9} - \frac{2}{9} s + \frac{1}{9} s = \frac{2}{9} - \frac{2}{9} s
