It is 12=12/4-7=9
When you are solving a 2-step equation, you do the opposite of a 1-step equation. You do addition and subtraction first, then the multiplication second. Example: 2x + 9=16 -9 -9 2x=7 Now it's a 1-step equation 2x=7 /2 /2 Your answer would be 3.5 To check all you do is replace the variable with your answer. 2x + 9=16 2(3.5) + 9=16
5x-2x=9
An equation is a statement that two things are equal; it has an equal sign which looks like this: = So if, for example, 2x + 5 = y4 - 27, that's an equation. A collection of numbers and/or letters that does not have an equal sign would be an expression. For example, 3x(9 + x).
That's not an equation, it has no equal sign. It seems that when typing a question, the equal sign and some other signs get eliminated on this site; you'll have to write the equal sign as "equals" or "equal"; similarly for some other special symbols.
If: x/8 +2 = 9 then x = 56
A multi-step equation that equals 27 could be (3x + 9 = 27). To solve for (x), first subtract 9 from both sides to get (3x = 18), and then divide by 3 to find (x = 6).
One example of a multi-step equation that equals 23 is (2x + 5 = 23). To solve for (x), first subtract 5 from both sides, resulting in (2x = 18). Then, divide both sides by 2 to find (x = 9). Therefore, the equation satisfies the condition of equaling 23 when solved.
n = 9

h5-9-19 is not an equation. An equation must have an equal sign.
Without an equality sign the given expression can't be considered to be an equation. But if you mean: 3(x+1) = 9 then 3x+3 = 9 and 3x = 9-3 so 3x = 6 => x = 2
it is 3x3 not that hard
5x-2x=9
the first step in solving the equation is to subtract the nine from the three. you will get negative 6.
3x+3=30 X=9
One out of many examples of two step equations that equal 29 is: (9 x 3) + 2
To be called an "equation", it must have an equal sign.
