Solving non -linear systems are placed.

And we're given that two loans, 1 at 8%, and 1 at 10%, are taken out by the students.
00:14
Now we need to write our equations, so we're going to let x be the variable amount for the 8 % loan and y b the amount for the 10 % loan.
00:25
And we'll give them that these total to 3 ,000.
00:28
So we get x plus y equals 3 ,000.
00:33
Next, we're given the amount of interest, so for 8%, that's the interest gained from the birth loan, and that's the interest gain for the 10 % loan, and this is equal to 264.
00:56
Next, we need to solve, so we're going to multiply this equation by 10, give 0 .8x plus y, plus 2 ,640, and we're going to subtract this equation from this one.
01:12
It is 0 .2x, suppose 1 minus 0 .8 is 0 .2...
