x is the number of adults and y is the number of children.
x + y = 12
<span>14x + 10y = 140
lets multiply the first equation by -10 and then add it to the second equation:
-10x - 10y = -120
</span>14x + 10y = <span>140
</span>-----------------------
4x + 0 = 20
x = 20/4
x = 5
then substitute in the original equation:
x + y = <span>12
</span>5 + y = <span>12
</span>y = 12 - 5
y = 7
therefore there were 5 adults and 7 children
Answer:
y - 1 = 3 ( x - 2)
Step-by-step explanation:
The formula for point slope form is y-y1=m(x-x1)
Just substitute the given information into the equation to get your answer.
(reminder m=slope, y1=the given y value, x1= the given x value)
