Solve by elimination.
The goal is to cancel out one of the variables in order to easily solve for the other variable.
Do this by changing the equations so that the coefficients of either x or y add up to 0.
Notice the coefficients of y are 3 and 3, if we make one of them negative then they add up to 0. 3+ (-3) = 0
Multiply 2nd equation by -1.
6x +3y = 9
-2x -3y = -1
__________
4x +0y = 8
Solve for x
4x = 8
x = 8/4 = 2
Plug x=2 back into one of original equations to find y.
---> 2(2) + 3y = 1
---> 4 + 3y = 1
---> 3y = -3
---> y = -1
Therefore solution is (2,-1)

Answer:
Interest Chaney earns after 3 years is $56.85
Step-by-step explanation:
Given:
Amount deposited = $1435.73
Simple annual interest rate = 1.32% = 1.32/ 100 = 0.0132
To find: Interest after 3 years
We know that the formula to calculate the interest amount is
Simple interest (S.I.) =
where,
P is the initial amount deposited
r is the rate of simple interest in percentage
t is the time in years for which interest is to be calculated
Substituting the known values in the formula, we get
S.I =
= 56.85
Hence the interest Chaney earns after 3 years is $56.85
