Answer:
Therefore the amount in the 4% savings account = $550
Step-by-step explanation:
i) the total amount = $1500
ii) let the amount placed in the 4% interest savings account = x
iii) let the amount placed in the 5% interest savings account = y
iv) therefore fro i) we can say x + y = 1500
v) the total interest gained = $69.5
vi) therefore we can write 0.04x + 0.05y = 69.50
vii) multiplying equation vi) with 100 we get 4x + 5y = 6950
viii) Multiplying the equation in iv) by 5 we get 5x + 5y = 7500
ix) Subtracting equation in vii) from equation in viii) we get x = $550
x) Therefore the amount in the 4% savings account = $550
You can type those equations into the desmos graphing calculator online! find the feasible region (where all the colors overlap) and find the vertices then fill them into the objective function! if you have any more questions then let me know!!

Step-by-step explanation:
Answer:
what you do is you want to get the x by it self so you would subtract the x and put it on the other side. like this: 10y=-9-x. OK so you would subtract -9 and put it on the other side like this: 9 + 10y=-x. but you can't have a negative x so u would do -9 + 10y=x.
