2f + 2v = $12.50
8f + 2v = $29.00
-2f. - 2v = -12.50
8f + 2v = 29.00
6f = $16.50
f= $2.75 each flower bouquet
2(2.75) + 2v = 12.50
5.50 + 2v = 12.50
2v = $7.00
v = $3.50 each vase
x<=4
x is less than or equal to four
children less than or equal to four can ride the train for free
<span>The equation to solve seems to be 1 / (2x) + 3 = - x + 7. Which is solved using this steps: First multiply both sides times 2x (this implies that x cannot be zero). As result you get: -1 + 6x = -2x^2 + 14x. Second group terms in the left side: 2x^2 + 6x - 14x - 1 = 0 => 2x^2 - 8x - 1 = 0. Third, use the quatratic equation to solve and you get two answers: x= -0.121 and x = 4.121</span>
