Subtract that number from. Your welcome dumb
Like this. You call your number "x", and write:x = 0.435435... (equation 1) 1000x = 435.435435... (equation 2) Then, you subtract equation 1 from equation 2, and solve for "x". This will give you "x" as a fraction. Note: The factor 1000 was chosen because the period (number of repeating digits) is 3, and 1000 has 3 zeros.
You solve this as follows. You call your number "x", and write:x = .323232... (equation 1) Then you multiply this equation by 100 (a one, followed by two zeros - this is because the length of the period is 2), and get: 100x = 32.323232... (equation 2) Now you can subtract equation 1 from equation 2, and solve for "x". This will give you "x" as a fraction.
Lets say that the equation is: 2+3x+2x=222+5x=22 Combine Like Terms.2-2+5x=22-2 Subtract 2 from each side.5x=20 Simplify.5x/5=20/5 Divide 5 on each side.x=4 Simplify.Check...2+3x+2x=22 x=42+3(4)+2(4)=22 Substitute x for 4.2+12+8=22 Multiply and Divide first from left to right.14+8=22 Add and Subtract from left to right.22=22Should you have an equation with higher order (like x2) then different methods, like factoring or the quadratic formula will apply.Eh?
X + 6 = X + 8This is a nice example of an equation that has no solution.If you subtract 'X' from both sides of the "equation", it says: " 6 = 8 " .This should immediately lead us to suspect that something here is not kosher, (that is to say, unorthodox).
lets say we have a equation : 3x + 4=13 the whole thing is called the equation. the 3 in the 3x is the coefficient. x is the variable, 18 is the solution
Set up the equation and solve: x + 5 = -13 (next subtract 5 from each side of the equation to solve for x) x = -18

Set up the equation: x + 19 = 76 (then subtract 19 from each side to find the value of x) x = 57
x + 22 = 104.8 Subtract 22 from each side of the equation: x = 82.8
The equation to represent the cube of the difference of a number x and 7 is (x - 7)^3. This means that you subtract 7 from the number x, and then raise the result to the power of 3 to get the cube of the difference.
2x - 6 = 3x + 3: * Firstly, subtract 2x from both sides of the equation: -6 = x + 3 * swap the equation, so that "x" is on the left-hand side (to make things easier): x + 3 = -6 * subtract 3 from both sides of the equation, to give: x = -9
Subtract that number from. Your welcome dumb
4 - x = 24 = 2 + x (add x to both sides of the first equation)2 = x (subtract 2 from both sides of the second equation)
Call this fraction "x". In that case:x = 0.123123... (equation 1) 1000x = 123.123123... (equation 2) Subtract equation 1 from equation 2, and solve for "x". That gives you the number as a fraction.
Here is an example: x + 5 = 5If you subtract five from both sides, you get x = 0, which is an example of getting 0 as a solution for an equation.
