We can solve this by following the steps I'm about to explain.
1) Write the equation out.
• 4x + 1 = 2x - 3
2) Get the numbers and variables to their own side.
• 4x + 1 = 2x - 3
• 4x + 1 - 1 = 2x - 3 - 1
• 4x = 2x - 4
• 4x - 2x = 2x - 2x - 4
• 2x = -4
3) Perform the opposite operation that is holding the variable together. (2x = 2(x) so we're multiplying - we need to divide)
• 2x = -4
• 2x/2 = -4/2
• x = -2
4) Check your solution
• 4x + 1 = 2x - 3
Substitute the value of X for every x in the equation.
• 4(-2) + 1 = 2(-2) - 3
• -8 + 1 = -4 - 3
• -7 = -7
It is no tpossible to find the square root of an unknown number. You can, however, represent it as x0.5 or √x so that the value of the square root can be evaluated when the value of x is known.
f(71.19) = 71 where int(x) is the integer value of a number
You cannot because the expression still contains the unknown variable y.
find a number whose valuw equals the number of letters
If you mean... -7+x*2=23 then x = 15. Done without the aid of a calculator ! The value of 'x' (the unknown number) MUST equal 30, because 30-7=23 - SO, half the unknown number must be 15!
Treat this as an equation to find the value of x 5/6x = 100 Multiply both sides by 6: 5x = 600 Divide both sides by 5: x = 120 So the value of the unknown number is 120.

Simply reverse the question and you find that 4 + 6, which is 10 equals half of the unknown number. 10 x 2 = 20, which must therefore be the unknown number.

just to find out our given unknown resistance value or to put it another way, To find the value of the unknown resistor attached.
Let the unknown number be x: 45x = 4950 Divide both sides of the equation to find the value of x: x = 110

I dont think you can other than the ! Unknown or the ? Unknown in hg or ss
You can do a reverse phone number lookup in several ways. For example if your landline provider has number ID this can provide you with the number received. Other ways are to enter the unknown number on line to find if the unknown number is recorded.
