Step-by-step explanation:
Translate the verbal statements into a system of linear equations: Fatima invested a total of $1000 in two simple-interest bank accounts. One account paid 5% annual interest; the other paid 6% annual interest. The total amount of interest she earned after 1 year was $56
Simple interest formula =
I = PRT
We are to find the Amount = Principal invested
For Account 1
I1 = P × 5% × 1
= 0.05P
Account 2
I2 = P × 6% × 1
= 0.06P
Therefore:
0.05P + 0.06P = $56
Solve for z:-
z - 12 = -9
z = ?
Inverse Operation
-9 + 12 = z
-9 +12 = 3
z = 3
Check:-
z - 12 = -9
z = 3
3 - 12 = ?
3 - 12 = -9
Correct!
z = -9
