An equation of a line (Linear function, first-degree function). It's a line with a slope of 1/3, meaning for every 3 increase in x, increases by 1.
It depends on how y depends on x.
Y = 4/x^2
If x+y = 3 and y times x = 2 then y = 1.
To solve for x when z equals y divided by x, you can rearrange the equation to isolate x. Start by multiplying both sides by x to get xz = y. Then, divide both sides by z to solve for x, giving you x = y/z. This is the solution for x when z equals y divided by x.
y=x y=6-x Set the two equations equal to each other to yield a solution: x=6-x 2x=6 x=3 x=3 will satisfy both equations, that is plugging in x=3 will give the same value for y y=(3)=3 y=6-(3)=3

x=y
To find what is divided by what equals 21, you can express it as an equation: ( x \div y = 21 ). This means that ( x = 21y ). For example, if you choose ( y = 1 ), then ( x = 21 ); or if ( y = 3 ), then ( x = 63 ). There are infinitely many pairs of numbers that satisfy this equation.
One simple solution is y = (x + 5/2)*(x - 2)*(x - 3/2) You can expand that into its cubic form, if you wish.
x=4 y=x+3 y=4+3 y=7
