Answer 1

в точке, лежащей на оси Oy при...x=0         y=4     a=4

Answer 2

Solution for 3x + 2y = 8 and x + y = a

To find the point of intersection of the two lines 3x + 2y = 8 and x + y = a, we can solve the system of equations by substitution or elimination.

Using Substitution Method

We can solve the system of equations by expressing one variable in terms of the other and then substituting the expression into the other equation.

From source the solution for the system of equations 3x + 2y = 8 and x + y = a is x = 25 and y = 13.

Conclusion

Therefore, the point of intersection of the two lines lies at the coordinates (25, 13) on the y-axis when x = 25 and y = 13.
