6x + 4y = 24
2x - 4y = -8
We will use the addition method in solving this system of equation.
6x + 4y = 24
+ (2x - 4y = -8)
8x + 0 = 16
8x = 16
x = 16/8
x = 2
Let us substitute x by its value to get the value of y.
6x + 4y = 24
→ 6(2) + 4y = 24
12 + 4y = 24
4y = 24 - 12
4y = 12
y = 12/4
y = 3
2x - 4y = - 8
→ 2(2) - 4y = - 8
4 - 4y = - 8
-4y = - 8 - 4
-4y = -12
y = -12/-4
y = 3
So x = 2 and y = 3. → (2,3)
The true statement among the choices are:
A) The ordered pair that is the solution to the system lies in Quadrant I .
<span>B) The y-coordinate of the solution is 3.
</span><span>D) The x-coordinate of the solution is 2.</span>
Answer:
y=-x+5 if parallel and perpendicular
if needed in point slope form : y-7 = -1(x+2)
Step-by-step explanation:
Take the current year and subtract is from the initial year, so
This year is 2016, your are trying to find age if born in 1983
2016
- 1983
-------------
33
You would be 33 years old if you were born in 1983 as of 2016.
