Question

X+10/61+2=9.1怎样解？

Answer 1

解：解方程此方程的解为x = 4231/610

X+10/61+2=9.1

x + 10/61 + 2 = （9×10+1）/10
x + 10/61 + 2 = 91/10
x = 91/10 - 2 - 10/61
x = 5551/610 - 1220/610 - 100/610
x = 4331/610 - 100/610
∴x = 4231/610
答：此方程的解为x = 4231/610

Answer 2

x+10/61+2=9.1
x=9.1-2-10/61
x=7.1-10/61
x=6+671/610-100/61
x=6+571/610
x=6又571/610
那么，我们可以通过解方程得到x=6又571/610

Answer 3

X+10/61+2=9.1
X=7.1-10/61
X=71/10-10/61
X=4331/610-100/610
X=4231/610

Answer 4

X+10/61+2=9.1
→61X+10+122=9.1*61=5551/10
→61X=555.1-10-122=423.1
→X=423.1/61≈6.936
