9.5x+2*62+31=240

解答

9.5 x + 2 \cdot 62 + 31 = 240

解答

x = \frac{170}{19}

+1

十进制

x = 8.94736 \dots

求解步骤

9.5 x + 2 \cdot 62 + 31 = 240

数字相乘:

2 \cdot 62 = 124

9.5 x + 124 + 31 = 240

数字相加:

124 + 31 = 155

9.5 x + 155 = 240

在两边乘以

10

95 x + 1550 = 2400

将

1550

到右边

95 x = 850

两边除以

95

x = \frac{170}{19}

solvefor x,5y-5=2x-5

so l v e f or x, 5 y - 5 = 2 x - 5

solvefor a,a^2+b^2=(a-b)(a+b)

so l v e f or a, a^{2} + b^{2} = (a - b) (a + b)

(x+2)+5(x+5)=4(x-8)+26(-2)

(x + 2) + 5 (x + 5) = 4 (x - 8) + 26 (- 2)

(x-1)*(x+1)-(x-2)*(x-3)=5

(x - 1) \cdot (x + 1) - (x - 2) \cdot (x - 3) = 5
