x makes 7%
3000-x makes 2%
.07x+.02(3000-x)=130
.07x+60-.02x=130
0.05x=70; multiply both sides by 20
x=$1400@7%=$98
3000-x=$1600@2%=$32
Total is $130.

Two quantities, x and y.
x%2By=3000

The x quantity gave 2% profit.
0.02%2Ax

The y quantity gave 7% profit,
0.07%2Ay

Total amount of profit was 130 dollars.
0.02x%2B0.07y=130
