How much is one third minus two seventh?

Divide both sides and multiply by 21 to get 7-6 = 1

How to solve this equation? Can the process be more detailed? 6x + 8 = 7 (X-9)

6x+8=7（x-9）
6x+8=7x-63
7x-6x=63+8
x=71

How many degrees is sin1 equal to sin

180°/π

How to solve the equation x △ 60 + 75 + 8 = x △ 70 + 75

x÷(60+75)+8=x÷(70+75)
x/135+8=x/145
x/145-x/135=8
x =-15660

Secondary application of one variable in mathematics of grade two in junior high school
Let x1, X2 be the equation x ^ 2 - (K + 2) x + 2K + 1 = 0 about X, and X1 ^ 2 + x2 ^ 2 = 11. (1) find the value of K; (2) find a quadratic equation of one variable by using the relationship between root and coefficient, where one root is the sum of two roots of the original equation and the other is the square of the difference between two roots of the original equation

k=2

It is known that in the plane rectangular coordinate system, point a (8,0), point B (0,8) and moving point P start from the origin and move in the positive direction of x-axis at the speed of 1 unit per second
Q starts from point a and moves on ray AB at a speed of 2 units per second. Let the motion time be t
Is there a value of t such that △ Apq is an isosceles triangle?

Yes
1. T = 8 / 3 from 8-t = 2T
2. From 8-2 √ 2T = t, t = 8 / (1 + 2 √ 2t)
3. T = (16 √ 2 + 8) / 3 is obtained from (T-8) = 16 √ 2-2t
The above is the situation, please adopt it in time,
