solvefor x, x/2+y/5 =1

解答

求解

x, \frac{x}{2} + \frac{y}{5} = 1

解答

x = 2 - \frac{2 y}{5}

求解步骤

\frac{x}{2} + \frac{y}{5} = 1

将

\frac{y}{5}

到右边

\frac{x}{2} = 1 - \frac{y}{5}

在两边乘以

2

x = 2 - \frac{2 y}{5}

流行的例子

3 x + 42 = 60

2 x - 3 = - x - 9

(2x+1)(x-1)+x^2=3(x-1)(x+2)-3

(2 x + 1) (x - 1) + x^{2} = 3 (x - 1) (x + 2) - 3

5x-2x+(-x+6)=18-[-(7x+6)-(3x-24)]

5 x - 2 x + (- x + 6) = 18 - [- (7 x + 6) - (3 x - 24)]

(5d-2)/4+2= 8/5

\frac{5 d - 2}{4} + 2 = \frac{8}{5}
