1/2 x+1/2 x=x+1

解答

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

解答

无解

求解步骤

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

同类项相加:

\frac{1}{2} x + \frac{1}{2} x = 2 \cdot \frac{1}{2} x

2 \cdot \frac{1}{2} x = x + 1

分式相乘:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

\frac{1 \cdot 2}{2} x = x + 1

约分:

2

x \cdot 1 = x + 1

乘以:

x \cdot 1 = x

x = x + 1

将

x

0.9x+5.1x-7=2(2.5x-3)

0.9 x + 5.1 x - 7 = 2 (2.5 x - 3)

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

so l v e f or x, \frac{x}{2} + \frac{y}{5} = 1

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
