4X = 12

4X = 12

x/5=12
x=60

0.1 (1 + x) minus 0.2 (0.4x-0.5) = 1 / 2

0.1 (1 + x) minus 0.2 (0.4x-0.5) = 1 / 2
10+10x-2x+2.5=0.5
8x=-12
x=-3/2

How can X-2 / x + 4 plus 2-x 4x be X-2 / x minus X-2 / 4x

(x square + 4) / (X-2) + 4x / (2-x)
=(x + 4) / (X-2) - 4x / (X-2)
=(x-4x + 4) / (X-2)
=(X-2) square / (X-2)
=x-2

What is the square of 2 plus 2x? What is the square of 2 times 2? What is the square of 2 times 3x?

A,4x² B,8 C,6x²

What is 3x (x-1) - x (3x-5) = 8x

3（X*2）-3x-3（X*2）+5x=8x
2X=8X
X=0

How to solve this equation

Add the two equations to get y. take one equation to get X

If the power of 3x + 2 of 5 is equal to 1, find the value of X?
RT

Any number to the power of 0 equals 1, so 3x + 2 = 0, x = - 2 / 3

Why are the numbers that square equals itself 0 and 1,

That is to find the value of X which is consistent with x ^ 2 = X
X ^ 2-x = 0
Extract the common factor and get x (x-1) = 0
The solution is x = 0 or x = 1
So the numbers where the square equals itself are 0 and 1

The square of a number is equal to this number plus one. What is this number?
This is a university problem, no one in the class thought of it, it seems that no one thought of it
Seems to be a mistake?

x^2=x+1
Solve this equation
X = (1 + - radical 5) / 2

If the square of a number equals 5, then the number is zero

This number is ± √ 5
