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

What if the number is unknown to find square root square root?
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.
What divided by what equals 4?

Explain why you cannot find a numerical value for the expression 4x - 5y for x equals 3?
You cannot because the expression still contains the unknown variable y.
If fx equals int x find the function value f71.19?
f(71.19) = 71 where int(x) is the integer value of a number
What is the absolute value of the sum of -7 and twice a number is 23 Find the number?
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!

When 4 is subtraced from one half of an unknown number it is equal to 6 the number is?
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.
What times 16 equals 140?
Well, darling, if you want to know what times 16 equals 140, the answer is 8.75. So, if you're looking to impress someone with your math skills, go ahead and drop that little nugget of knowledge on them. You're welcome.
80 percent of what number equals 40?
To find the number, you would set up the equation 0.80x = 40, where x represents the unknown number. To solve for x, you would divide both sides by 0.80 to isolate x, giving you x = 40 / 0.80. Therefore, the number is 50.
