K = 1.2 Short answer.
It's going to seem odd, but one of the ways you could solve this is by multiplying the first equation  by 4. I'll tell you why in a moment.

4(0.3x - 0.7y = 1)     Now remove the brackets.

1.2x - 2.8y = 4          If you want there to be no solution, the way to do it is the make k = 1.2 The second equation becomes.
1.2x - 2.8y = 3

I'm going to give you the graph of this so you will see why there is no solution. Do you see why?

The lines are parallel!! they never meet.

Supposed five plain hamburgers cost the same as three super burgers. Also suppose that one super burger cost $.30 more than one
noname [10]

Answer:

1 plain = $0.75; 1 cheese = $0.95; 1 super = $1.25

Step-by-step explanation:

We have three conditions

(1) 5P = 3S

(2)  S = C + 0.30

(3)  P = C – 0.20                           Substitute (3) into (1)

=====

(4)   5(C – 0.20) = 3S                   Substitute (2) into (4)

      5(C – 0.20) = 3(C + 0.30)     Remove parentheses

         5C – 1.00 = 3C + 0.90       Add 1.00 to each side

                    5C = 3C + 1.90        Subtract 3C from each side

                    2C = 1.90                 Divide each side by 2

                      C = $0.95              Substitute C into Equation (2)

=====

                      S = 0.95 + 0.30

                      S = $1.25               Substitute C into Equation (3)

=====

                     P = 0.95 – 0.20

                    P = $0.75

1 plain = $0.75; 1 cheese = $0.95; 1 super = $1.25
