Formula For finding Simple interest= Profit x rate x time/ 100
Profit = $2,007 x Rate= 7% x Time = 16 years
2,007 x 7 x 16
__________ = 224,784 ÷100 = 2,247.84
100
Answer :- 2247.84
Step-by-step explanation:
Substitute the y in the 1st equation with the 2nd equation.
7x + 10(2x + 9) = 36
7x + 20x + 90 = 36
27x + 90 = 36
3x + 10 = 4
3x = -6
x = -2
So now we can find y.
y = 2x + 9 = 2(-2) + 9 = (-4) + 9 = 5.
So x = -2, y = 5.
