Question

3x-y=10

Answer 1

3х-у=10.  -у=10-3х.    у=3х-10.

Answer 2

The equation 3x - y = 10 is a linear equation in two variables x and y. It represents a straight line on the x-y plane.

To graph this equation, we can first find two points that satisfy the equation. We can do this by setting x to some value and solving for y, or setting y to some value and solving for x.

Let's choose to set x = 0:

3(0) - y = 10

Simplifying this equation, we get:

-y = 10

y = -10

So one point that satisfies the equation is (0, -10).

Now let's set y = 0:

3x - 0 = 10

Simplifying this equation, we get:

3x = 10

x = 10/3

So another point that satisfies the equation is (10/3, 0).

We can plot these two points on the x-y plane and draw a straight line passing through them to graph the equation. The graph will look like:

where the line passes through the points (0, -10) and (10/3, 0).
