If the formula 3-5x-3 5 + 2x is 1 less than 1 / 3-3x, then the value of X is
Yes - 1
When x is equal to (), 2x + 1 in 3 and 3x + 1 in 2 are opposite to each other
Opposite numbers add up to 0
(2x+1)/3+(3x+1)/2=0
Multiply both sides by 6
4x+2+9x+3=0
4x+9x=-2-3
13x=-5
x=-5÷13
x=-5/13

When x =? The values of Formula 1 / 3 (1-2x) and formula 2 / 7 (3x + 1) are equal. 1 / 3 represents one third and 2 / 7 represents two seventh
1/3（1-2x）=2/7（3x+1）
(1/3)-(2/3)x=(6/7)x+(2/7)
(6/7)x+(2/3)x=(1/3)-(2/7)
(32/21)x=1/21
x=1/32
When x =? The equation (1-2x) is equal to 2 / 7 (3x + 1)
It's a quarter indeed!
If the value of 3x - 2x + 6 is 8, then the value of 3x - x + 4 in 2 of the equation is? How to get the power of 3x + 2 + 2x = 2x? I see. Because 3x-x in 2 is twice 3x-2x, it becomes 1 / 2 times 2 + 4 = 5. Although I asked my classmates to come up with this question, today's midterm exam used your inspiration, so I gave it to you, Tao Xiaojun. In short,
3x-x + 4
children,
If you take one half of it, the coefficient of X becomes 2~
When x is equal to what number, the formula 2x-1 / 3 + 2 and - 1 are opposite numbers also Class assignments page 59 to 61
(2x-1/3+2)+(-1)=0
2x+5/3-1=0
2x=-2/3
x=-1/3
If the values of the algebraic expression 2x + 3 and X-5 are opposite to each other, then x=______ .
∵ the values of the algebraic formula 2x + 3 and X-5 are opposite to each other
∴2x+3+（x-5）=0，
The solution is: x = 2
3．
When x = 0___ The algebraic formula is 3-2x 2 and 2-x 3 is opposite to each other
From the meaning of the title,
3-2x
2=-2-x
3，
The solution is: x = 13
8．
When x =? The subunits 3-2x / 2 and 2-x / 3 are opposite numbers to each other
(3-2x) / 2 and (2-x) / 3 are opposite numbers to each other
∴(3-2x)/2+(2-x)/3=0
∴6-4x+4-2x=0
∴x=5/3
(3-2x) / 2 and 2-x / 3 are opposite numbers
∴(3-2x)/2+2-x/3=0
∴6-4x+12-2x=0
∴x=3
Look at your molecules
When x is equal to what number, the sum of 2 / 2 minus X and 3 / 3 x + 1 equals 2
2/2-x+3/x=2
X=3
