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?

What times 16 equals 140?
To find what times 16 equals 140, you would divide 140 by 16. This would give you the value of the unknown number. Therefore, 140 ÷ 16 = 8.75. So, 8.75 times 16 equals 140.
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

Five-sixths of a number equals 100 what is the number?
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.
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?
To find what times 16 equals 140, you would divide 140 by 16. This would give you the value of the unknown number. Therefore, 140 ÷ 16 = 8.75. So, 8.75 times 16 equals 140.

Multiply 45 with this number and you get 4950what is the number?
Let the unknown number be x: 45x = 4950 Divide both sides of the equation to find the value of x: x = 110
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!
