解答

6.2 d + 20 = 8.7 d

解答

d = 8

求解步骤

6.2 d + 20 = 8.7 d

在两边乘以

10

62 d + 200 = 87 d

将

200

到右边

62 d = 87 d - 200

将

87 d

para o lado esquerdo

- 25 d = - 200

两边除以

- 25

d = 8

solvefor x,d=sqrt((x_{1)-x_{2})^2+(x_{1}-x_{2})^2}

so l v e f or x, d = (x_{1} - x_{2})^{2} + (x_{1} - x_{2})^{2}

solvefor x,-2x-5y-10=0

so l v e f or x, - 2 x - 5 y - 10 = 0

solvefor x,4x+1/4 y=5

so l v e f or x, 4 x + \frac{1}{4} y = 5

solvefor x,4x+16y=16

so l v e f or x, 4 x + 16 y = 16

\frac{t + 3}{4} = \frac{63}{4}
