Answer:
x=4, y=1
Step-by-step explanation:
x + 3y = 7
x - 3y = 1
Add the equations together to eliminate y
x + 3y = 7
x - 3y = 1
---------------------
2x = 8
Divide by 2
2x/2 = 8/2
x = 4
Subtract the two equations to eliminate x
x + 3y = 7
-x + 3y = -1
----------------------
6y = 6
Divide by 6
6y/6 = 6/6
y =1
The introduction says to divide the guest number by 3.5 so your equation is 150/3.5 which equals just under 43. That’s your number.
Answer:
y=-2x+5. The slope (-2) of the equation is the same, so they are parallel.
