When Y1 = 2X-4, y2 = - 3x + 5 and what is the value of X, Y1 > Y2

When Y1 = 2X-4, y2 = - 3x + 5 and what is the value of X, Y1 > Y2

2x-4>-3x+5
5x>9
x>1.8
x> 8, Y1 > Y2

1. When 2y-x = 4, 5 (x-2y + x) - 60 = 2, let Y1 = 2x + 7 / 4, y2 = 3x-1, when what is the value of X, Y1 and Y2 are opposite numbers?
3. In the first round, there were 8 games and 16 points in total. How many games did you win?
4. The original price ratio of the first-class, second-class and third-class tickets announced by the Organizing Committee of League A is 12:8:5. A company spent 1500 yuan to buy the first-class tickets, two second-class tickets and four third-class tickets. How about the price of three kinds of tickets?
5. The train between a and B stops at a, B and C. the distance between the two stations is different
(1) How many different fares do you have to make?
(2) How many different kinds of tickets should be designed?
6. The ray OA, ob, OC and OD have the same vertex o, and ∠ AOB = 90 °, COD = 90 °, AOD = ∠ AOC

Let Y1 = 2x + 7 / 4, y2 = 3x-1, when what is the value of X, are Y1 and Y2 opposite to each other?
Y1 + y2 = 0, get (2x + 7 / 4) + (3x-1) = 0, get x = - 3 / 20
In the first round, there were 8 games and 16 points in total. How many games did you win?
Answer: one: win 5 games, draw 1 game, lose 3 games, a total of 16 points;
Two kinds: 4 victories, 4 draws, 0 losses, a total of 16 points!

It is known that Y1 = 2x + 3, y2 = 5-3x. When what is the value of X, Y1 is less than Y2 by 3?

From the meaning of the title
y2-y1=3
5-3x-(2x+3)=3
x=-1/5

Let Y1 = 2x + 7 of 4, y2 = 3x-1, when x is the value, Y1 and Y2 are opposite numbers

Because Y1 and Y2 are opposite numbers
So Y1 + y2 = 0
So (2x + 7) + (3x-1) = 0
Multiply by 4 at the same time
∴2x+7+12x-4=0
14x=-3
X = - 14 / 3

X=____ Y 1 = 3x-2 and y 2 = 2x + 4 are opposite numbers? (1 and 2 after y are in the lower right corner of Y. very small)

Y1+Y2=0
3X-2+2X+4=0
x=-2/5

Given that Y1 = 3x + 2, y2 = 4-x, when x is equal to what, make Y1 and Y2 opposite to each other

Let Y1 = - Y2
3x+2=x-4
x=-3

How to move 30-2x-3x + 15 = 4x + 36

45-5x=4x+36
45-36=5x+4x
9=9x
x=1

It is known that Y1 = 3x-2, y2 = 4x-7
(1) When x goes to what value, the values of Y1 and Y2 are equal? (2) when x goes to what value, Y1 is smaller than Y2 by 4? (3) when x takes what value, Y1 and Y2 are opposite to each other?

1、
y71=y2
3x-2=4x-7
x=5
2、
y2=y1+4
4x-7=3x-2+4
4x-7=3x+2
x=9
3、
y1+y2=0
3x-2+4x-7=0
7x-9=0
x=9/7

Given that Y1 = 4x + 8, y2 = 3x-7, when x takes what value, Y1 is smaller than Y2. 4, it's better to explain why
I have to hand in my homework tomorrow

y1=4x+8,y2=3x-7
Because Y1 is 4 less than Y2, y2-y1 = 4
So there are:
(3x-7)-(4x+8)=4
3x-7-4x-8=4
3x-4x=4+7+8
-x=19
x=-19
When x = - 19, Y1 is 4 times smaller than Y2

Given that Y1 = - x + 3, y2 = 3x-4, when x takes what value, Y1 = - x + 3, y2 = 3x-4
How to draw?

When Y1
