Question

(PLEASE HELP, NEED THIS URGENTLY)

A system of equation is shown.
5x+2y=245
y=x+6

Enter a numeric value to complete the solution of the system.

Answers

  1. Answer:
    y = 245 / 7, x = 29
    Step-by-step explanation:
    make both into ax + by = c format which is
    Math:
    5x + 2y = 245
    -5x + 5y = 30 <== 5 (- x + y = 6) to cancel out the x since it has a negative already.
    [(Side Note) if both were positive then you would need to do
    EX: – 5 (- x + y = 6)]
    Continued:
    7y = 275 ==> 7y/7 = 245/7
    y = 245 / 7
    Plug it in the most convenient one which has the equation y = x + 6
    and tweak it a bit
    x = y – 6
    x = 245 / 7 – 6 ==> 245 / 7 – 42 / 7
    x = 203 / 7 ==> 29
