You can use elimination by adding the two equations to "cancel out" one of the variables. in this example y will cancel out.
2x + y = 3
+
2x - y = 4
________
2x = 6
x = 3
now that we know our x value, we can plug it into one of the other equations to get our y value.
2(3) + y = 3
6 + y = 3
y = -3
your answer for this system is x=3, y=-3

Answer: Additional interest of $521.82 with a simple interest loan to sister generate.
Step-by-step explanation:
Since we have given that
Principal = $28000
Rate of interest at simple interest = 8%
Number of year = 1
so, Interest becomes,
Rate of interest compounded quarterly = 6%
Amount becomes,
So, Interest would be
Hence, Additional interest is given by
Hence, Additional interest of $521.82 with a simple interest loan to sister generate.
