2amx-4a=5mx+m-2ax

解答

2 am x - 4 a = 5 m x + m - 2 a x

解答

x = \frac{m + 4 a}{2 am - 5 m + 2 a}; a \neq = \frac{5 m}{2 ( m + 1 )}

求解步骤

2 am x - 4 a = 5 m x + m - 2 a x

将

4 a

到右边

2 am x = 5 m x + m - 2 a x + 4 a

两边减去

5 m x - 2 a x

2 am x - (5 m x - 2 a x) = 5 m x + m - 2 a x + 4 a - (5 m x - 2 a x)

化简

2 am x - 5 m x + 2 a x = m + 4 a

分解

2 am x - 5 m x + 2 a x : x (2 am - 5 m + 2 a)

x (2 am - 5 m + 2 a) = m + 4 a

两边除以

2 am - 5 m + 2 a; a \neq = \frac{5 m}{2 ( m + 1 )}

x = \frac{m + 4 a}{2 am - 5 m + 2 a}; a \neq = \frac{5 m}{2 ( m + 1 )}

3x-66+8x=-7x+13+x+23

3 x - 66 + 8 x = - 7 x + 13 + x + 23

1 + y = 1

7 = \frac{x}{9} + 8

5 h + 3 = 3 h + 11

2/3 n+8= 1/2 n+2

\frac{2}{3} n + 8 = \frac{1}{2} n + 2
