To isolate the variable ( z ) in the equation (-15z = 60), you would divide both sides of the equation by (-15). This operation will give you ( z = \frac{60}{-15} ), simplifying to ( z = -4 ).
divide by 51
You would use several properties. The first is that performing the same operation to both sides of an equation is valid. Next the multiplicative inverse property of 1/7 (with respect to 7).
An equation with a variable is a math problem with a missing number that you have to find out using some specific steps that you are taught. Example: 4+n=5. If you want to find out what the variable is, you have to do the OPPOSITE OPPERATION and find it out. So I would take the answer, and do the opposite operation and then the answer is the variable. Of course there are MUCH harder variable equations. :D
The idea is to "isolate" the variable, in this case "x", on one side. In this case, you would start by multiplying both sides of the equation by "x".

-g is really -1g so divide -1g by -1. what you do to 1 side, you have to do to the other side. so divide 35 by -1. the solution is g= -35
That depends entirely on the equation which has not been given but in general whatever is done on one side of an equation must be repeated on the other side in order to keep the equation in 'balance'
1-3m=24Improved Answer:-If you mean -8x = 312 then divide both sides by -8 and so x = -39But if you mean 8x = 312 then divide both sides by 8 and so x = 39

A dependent variable is usually on the side of the equation by itself. The independent variable usually has something being done to it. And, the dependent variable is usually written to the left of the equation.
The first step in solving an equation with a variable is doing the inverse operation. For example:4x + 8=32The first step would be to subtract 8 from 32. Since the operation is addition you would do the inverse which is subtraction. Then you would go on to divide 24 by 4Because 32-8= 24 Then you would get an answer of x=6 This answer is correct because 6 multiplied by 4 is 24
In mathematics, the term "subject" typically refers to the variable in an equation that is being solved for or isolated. For example, in the equation ( y = 2x + 3 ), if we want to make ( x ) the subject, we would rearrange the equation to ( x = \frac{y - 3}{2} ). The concept of a subject is crucial in algebra, where manipulating equations to isolate a variable is a fundamental skill.
