18.50+12.50x=4+2.50x

18.50+12.50x=4+2.50x

求解 18.50+12.50x=4+2.50x 方程:

简化
18.50 + 12.50x = 4 + 2.50x

解：
18.50 + 12.50x = 4 + 2.50x

求解变量 'x'.

移动所有条件 x 到左边，所有其他条件放右边.

添加 '-2.50x' 到等式的每一边.
18.50 + 12.50x + -2.50x = 4 + 2.50x + -2.50x

组合类似条件: 12.50x + -2.50x = 10x
18.50 + 10x = 4 + 2.50x + -2.50x

组合类似条件: 2.50x + -2.50x = 0.00
18.50 + 10x = 4 + 0.00
18.50 + 10x = 4

添加 '-18.50' 到等式的每一边.
18.50 + -18.50 + 10x = 4 + -18.50

组合类似条件: 18.50 + -18.50 = 0.00
0.00 + 10x = 4 + -18.50
10x = 4 + -18.50

组合类似条件: 4 + -18.50 = -14.5
10x = -14.5

两边除以'10'.
x = -1.45

简化
x = -1.45
