First you get the variables on one side and the constants on the other.
-2x = 14
Then you divide by -2 to get the variable alone.
x = -7

Previous poster was very wrong, 5n-3=17 5n=20 n=4
20 = y/5 is an equation. It is true, only if y = 100. To find this result systematically, multiply both sides of the original equation by 5.

There is none because it's not an equation
An equation never equals a number, but its solution often does.-- An equation with a solution of six: [ 3x - 14 = 4 ]-- An equation with a solution of three: [ 14 - 10x = -16 ]-- An equation with both solutions: [ x2 - 9x + 20 = 2 ]An equation that equals 6 is 10 - 4 = 6An equation that equals 3 is 10 - 7 = 3
Yes, it does.
x-14 = 20 x = 20+14 x = 34
what is the solution of x-5y=10 and 2x-10y=20

You haven't given the solution to the equation ! 3x + 20 = ? If you have the number for the question-mark - you can find the value of x ! For example in the equation 3x + 20 = 50... the value of x is 10.

The solution to the equation x - 6 - 20 is x - 26.
It is an equation in a single variable, x.And, although the question does not ask, the solution is x = 5.It is an equation in a single variable, x.And, although the question does not ask, the solution is x = 5.It is an equation in a single variable, x.And, although the question does not ask, the solution is x = 5.It is an equation in a single variable, x.And, although the question does not ask, the solution is x = 5.
