х = 1/3

Ответ :1/3

Answer 2

To solve the system of equations:

1. 3x + 9y = 4
2. x + 3y = 1

You can use the method of substitution or elimination. Let's use the elimination method in this case. First, you'll want to manipulate one of the equations to make it easier to eliminate one of the variables. You can multiply equation (2) by 3 to make the coefficients of y in both equations cancel each other out:

1. 3x + 9y = 4
2. 3x + 9y = 3

Now, subtract equation (2) from equation (1) to eliminate y:

(3x + 9y) - (3x + 9y) = 4 - 3

This simplifies to:

0 = 1

This means there is no solution to this system of equations. The two equations represent parallel lines in the coordinate plane, and they do not intersect. In other words, there are no values of x and y that simultaneously satisfy both equations.
