4x + 19 + 3x = - 5

4x + 3x + 19 = - 5 collect the like terms

7x + 19 = - 5

7x = - 5 - 19 bring 19 to the right

7x/ 7x = - 24/ 7

x = - 3.4

Adding the two equations
3x + 6y + 3x - 6y = 36+0
6x = 36
x = 6
.
subtracting second equation from first
(3x + 6y ) - (3x-6y) =36 -0
12y = 36
y = 3
.
therefore
x = 6 and y = 3
(6,3)

Chandler Heisinger buys a monthly metro card, which entitles him to unlimited subway travel in New York City, for $81 per month.

ANTONII [103]

Let $r$ be the number of rides Chandler takes in a month. Then the cost with the MetroCard is still $81, but the cost without the MetroCard is $2r$ . So we can set up an equation representing what we want: "The cost with a MetroCard of r rides in a month is less than the cost without a MetroCard." In equations,
$81\ \textless \ 2r \\ r\ \textgreater \ 81/2\ \textgreater \ 40 \\
r \geq 41$
Thus, at a minimum, Chandler must take 41 rides for his MetroCard to be cheaper than not having it.
