solvefor x,y+5= 2/2*(x-3)

解答

求解

x, y + 5 = \frac{2}{2} \cdot (x - 3)

解答

x = y + 8

求解步骤

y + 5 = \frac{2}{2} (x - 3)

交换两边

\frac{2}{2} (x - 3) = y + 5

使用法则

\frac{a}{a} = 1

\frac{2}{2} = 1

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

乘以:

1 \cdot (x - 3) = (x - 3)

x - 3 = y + 5

去除括号:

(a) = a

x - 3 = y + 5

将

3

到右边

x = y + 8

r^1=[(1.1)(2.2)(3.3)(4.4)]

r^{1} = [(1.1) (2.2) (3.3) (4.4)]

2x=9,p(x)=0.62,n=1

2 x = 9, p (x) = 0.62, n = 1

x/(1.6+2.8)=8.8

\frac{x}{1.6 + 2.8} = 8.8

d= 1/((sqrt(5)+2))

d = \frac{1}{( 5 + 2 )}
