4.9k+6-1.2k=8+3.7k

解答

4.9 k + 6 - 1.2 k = 8 + 3.7 k

解答

无解

求解步骤

4.9 k + 6 - 1.2 k = 8 + 3.7 k

对同类项分组

4.9 k - 1.2 k + 6 = 8 + 3.7 k

同类项相加:

4.9 k - 1.2 k = 3.7 k

3.7 k + 6 = 8 + 3.7 k

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

3.7 k \cdot 10 + 6 \cdot 10 = 8 \cdot 10 + 3.7 k \cdot 10

整理后得

37 k + 60 = 80 + 37 k

将

60

到右边

37 k = 37 k + 20

将

37 k

(x+6)^2=(15-x)^2

(x + 6)^{2} = (15 - x)^{2}

2 x - 6 = 3 (x - 4) + 12

- 8 (6 - 6 k) = 7 k - 7

0.5 - 0.5 a = - 4.5

9 x + 2 = 119
