3x-6y=20 and. 2x-4y=3. I have three problems kind of like this one.?

Please walk me through each step. I really need to learn how to do these. Thank you in advance.

Sorry wrong problem. I just had to know if it was dependent, consistent, inconsistent or independent.

  • Here, to solve the system just multiply the first equation by 2 and the second equation by -3 ....

    It is so 6x -12y = 40

    -6x +12y = -9 ==> 0 = 31 ... it is not true, then there is no answer. The system has no solution.

  • I not sure if ur looking for x & y.

    3x - 6y = 20

    x - 6y = 6.67

    x - y = 6.67/6

    x - y = 1.11 .

    x = 1.11 + y

    -------------------------------

    2x - 4y = 3

    x - fy = 3/2

    x - y = 3/8

    x = 3/8+y.

    x.x

  • meow meow meow that's how xDDD
