The exponential decay function could be the model of the situation comparing what I said do not utilize because the user is trying to acoses the points
Answer:
(2, - 3)
Step-by-step explanation:
given the 2 equations
5x + 3y = 1 → (1)
7x + 3y = 5 → (2)
multiply all terms in (1) by - 1
- 5x - 3y = - 1 → (3)
add (2) and (3) term by term to eliminate the term in y
(7x - 5x) + (3y - 3y) = (5 - 1)
2x = 4 ( divide both sides by 2 )
x = 2
Substitute x = 2 in either (1) or (2) for corresponding value of y
(2) : 14 + 3y = 5 ( subtract 14 from both sides )
3y = - 9 ( divide both sides by 3 )
y = - 3
solution is (2, - 3)
So first add 5 to both sides so you have x ÷ 4 = -3
Then multiply both sides by 4 to get x = -12
Hope this helps!
