4 tootsie rolls, 3 lollipops, 5 hersheys kisses, 6 starbursts......for a total of 18 pieces of candy.
now...there are 3 lollipops.....and 18 total pieces of candy.....so the probability of selecting a lollipop is : 3/18 which reduces to 1/6
Y = -3x - 1......so we sub in -3x - 1 in for y in the other equation
2x + 5y = 12
2x + 5(-3x - 1) = 12....now distribute the 5 through the parenthesis
2x - 15x - 5 = 12...add 5 to both sides
2x - 15x = 12 + 5..combine like terms
-13x = 17...divide both sides by -13
x = -17/13
now sub in -17/13 for x in the other equation
y = -3x - 1
y = -3(-17/13) - 1
y = 51/13 - 1
y = 51/13 - 13/13
y = 38/13
so the solution is (-17/13, 38/13)
