RafaNo, 4-x is not the same as x 4. In the expression 4-x, the subtraction operation is being applied to subtract x from 4. In the expression x 4, the operation being implied is multiplication, with x being multiplied by 4. The order of the operands and the operation matters in mathematical expressions.
Well, honey, let me break it down for you. The expression "4-x" is not the same as "x 4." In the first expression, you're subtracting x from 4, while in the second one, you're multiplying x by 4. So, no, they are not the same thing. It's like comparing apples to Oranges, darling.

What is the solution for the inequality -4x plus 2 6?
-4x + 2 = 6 -4x = 6 - 2 -4x = 4 x = 4 / -4 x = -1
If 4x - 1 equals 15 what is x?
4x - 1 = 15 Therefore, 4x = 16 x = 16/4 Therefore, x = 4
Square root of x squared plus 4 equals 4x?
Keep in mind the square root of x squared equals the absolute value of x. So, solving this equation for x involves the following: sqrt(x2)+4=4x |x|+4=4x Solving for |x| yields: |x|=4x-4 Using x=4x-4: -3x=-4, x=4/3. Using x=-(4x-4): x+4x=4 x=4/5 Checking both with the original equation shows that |4/3|+4=16/3=4*4/3, so x=4/3. However, |4/5|+4=24/5, which does not equal 4*4/5, so x does not equal 4/5. This means there is only one solution, x=4/3.
What is the answer to 5x - 2 4x plus 4?
If your equation is 5x-2=4x+4 Then this is how you solve it... 5x-2=4x+4 5x-2+2=4x+4+2 5x=4x+6 5x-4x=4x-4x+6 x=6 Your x=6
