Get two slaves. Give one equation to each slave. Say, "Go!"
7y = 3y - 12 4y = -12 y = -3
The number 3 equals x when it has the same value in an equation. This is used to help solve a specific problem in math where certain variables are unknown.
In a math equation, something equals something else. You haven't given any equation to work with. I'm thinking you're looking to find 'x' when 'y' equals 2, when 'y' equals 3, etc. But we need some more info to help you.
Give us the whole equation, and we can help.
If you mean 3x2+4x-2 = 0 then it can be solved by means of the quadratic equation formulla
You can take the logarithm on both sides of an equation. The real trick is to figure out when this will help you to solve the equation, and when not.
It combines like terms and results in the least amount if variables to solve for
It does not help you.
3 - x = 12x - 1 Add x to both sides of the equation: 3 = 13x - 1 Add 1 to both sides of the equation: 4 = 13x Divide both sides of the equation by 13: 4/13 = X
