无解

求解步骤

1.5 - (9 - 4 x) = 0.5 (8 x + 1)

To eliminate decimal points, multiply by 10 for every digit after the decimal pointThere is one digit to the right of the decimal point, therefore multiply by

10

1.5 \cdot 10 - (9 - 4 x) \cdot 10 = 0.5 (8 x + 1) \cdot 10

整理后得

15 - 10 (9 - 4 x) = 5 (8 x + 1)

展开

15 - 10 (9 - 4 x) : 40 x - 75

展开

5 (8 x + 1) : 40 x + 5

40 x - 75 = 40 x + 5

将

75

到右边

40 x = 40 x + 80

将

40 x

solvefor x,-6x-2y=4

so l v e f or x, - 6 x - 2 y = 4

so l v e f or x, f = 0

2 (x - 4) + 3 x = 5 x + 7

6 (x - 2) = 4

solvefor x, x/2-5=3

so l v e f or x, \frac{x}{2} - 5 = 3
