Emesto tried to determine the solution for the system of equations using substitution his work is shown below x-y=7 3x-22y=8 in which step did Emesto make the first error

29 mil

step-by-step explanation:

d will be the best answer

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)
