It depends on what y is.
y = 100 - 4x ( a ) Find the value of y when x = 20.
The Sine function (abbreviated sin) takes an angle and gives a ratio which is based on the sides of a right triangle. If you have a right triangle, and one of the angles (not the right angle) is labeled y then sin y equals the length of the side opposite of angle y divided by the length of the hypotenuse. The hypotenuse of a right triangle is the longest side, and is always opposite of the right angle.
Y for Yes
Oh, what a lovely question! When x is 3, we simply substitute x with 3 in the equation to find the value of y. It's like adding a happy little tree to your painting - just plug in 3 for x and see what beautiful value of y comes out!

X as a percentage of Y is 100*X/Y.
Choose any value for x. Calculate 8x to get the corresponding value for y.
If you substitute some value for x, you can calculate the corresponding value for y.If you don't know the value for x and y, you have a relationship between two variables, that can not be further simplified.If you substitute some value for x, you can calculate the corresponding value for y.If you don't know the value for x and y, you have a relationship between two variables, that can not be further simplified.If you substitute some value for x, you can calculate the corresponding value for y.If you don't know the value for x and y, you have a relationship between two variables, that can not be further simplified.If you substitute some value for x, you can calculate the corresponding value for y.If you don't know the value for x and y, you have a relationship between two variables, that can not be further simplified.
Solve for y; calculate a few sample points (plug in a value for x, then calculate the corresponding value for y); plot on the graph. Two points should be enough in theory (this equation is a straight line), but a third point helps you confirm that your calculations are correct.Solve for y; calculate a few sample points (plug in a value for x, then calculate the corresponding value for y); plot on the graph.

!x-y! first calculate x-y, then calculate av.
y = 5x is the equation of a line. Subtitute any value for "x", then calculate the corresponding value of "y", which in this case is simply the value of "x" multipled by 5.
Find (or calculate) the equation of the line. Select any value of x. Calculate the corresponding value for y using the equation. Then (x, y) is a point on the same line.
y=0.5x is an equation that cannot be solved unless you have a known value for either y or x.
Choose any value for "x", replace that in the equation, and calculate the corresponding value for "y".
