0.08%2850%29+%2B+0.40x+=+0.20%2850+%2B+x%29+

4+%2B+0.40x+=+10+%2B+0.20x+

+0.40x-0.20x=10+-4

+0.20x+=6+

+x=6%2F0.20+
+x=30+

check it on a graph:
+graph%28+600%2C+600%2C+-10%2C+35%2C+-10%2C+15%2C+0.20x+-6%29+
and algebraically:

0.08%2850%29+%2B+0.40x+=+0.20%2850+%2B+x%29+.....plug in +x=30+

0.08%2850%29+%2B+0.40%2A30+=+0.20%2850+%2B+30%29+

4+%2B+12+=+0.20%2880%29+

16=16+
