Answer:
5,1
Step-by-step explanation:
7x + 4y = 39
2x + 4y = 14
since, the 4y same for both equation then we can eliminate the 4y by subtracting the two equation
7x + 4y = 39
2x + 4y = 14
---------------- -
5x + 0 = 25
5x = 25
x = 25/5 = 5
then we can input (subtitute) the value of x into the equation, I choose 2x + 4y = 14
2x + 4y = 14
2(5) + 4y = 14
10 + 4y = 14
4y = 14 - 10
4y = 4
y = 4/4 = 1
or if your teacher ask you to use elimination to find the value of x we can write like this
7x + 4y = 39
2x + 4y = 14
make the coeficient of x in both equation same
7x + 4y = 39 (x2)
2x + 4y = 14 (x7)
so
14x + 8y = 78
14x + 28y = 98
--------------------- -
0 - 20y = -20
-20y = -20
y = (-20)/(-20) = 1 (same answer right)
so the correct answe is
(5,1)
Answer:
yes
Step-by-step explanation:
I'm not entirely sure what your question is, but x is directly proportional to y, meaning as as x increases at a constant rate, y also increases at a constant rate.
