Answer:
$2.00/5= 0.4
so 40 cents
Step-by-step explanation:
Multiply the equation 2x + y = 1 by 3 to obtain same coefficients of y.

Substract the equation 3x + 3y = 15 from 6x + 3y = 3 to eliminate the terms of y.

Substitute -4 for x in the equation 2x + y = 1 to obtain the value of y.

So solution of equations is (-4,9).
