If the first piece of land Carl bought for x$, then the second piece he bought for (120,000-x)$
If he made a profit of 15% when sold the first plot, so profit was 0.15x$
When he sold the second he lost 10%, so he lost 0.1*(120,000-x)
His total profit was 0.15x-0.1*(120,000-x)
His total profit was 5,500
equation

the first piece of land Carl bought for 70,000$
the second plot he bought for 120,000-70,000=50,000$
