Question 132434
Hello.  Thanks for writing.  We have an equation here and we must solve for x.

0.04x + 0.06(30)= 0.20(49)

The first thing to do is multiply 0.06 by (30)and then 0.20 by (49).

Let's do that right now!

0.06 times(30) = 1.8

THEN:

0.20 times (49) = 9.8

We now have a new equation:

0.04x + 1.8 = 9.8

We now subtract 1.8 from 9.8

0.04x = 9.8 - 1.8

0.04x = 8.0

To find x, simply divide 8.0 by 0.04 and that's it.

x = 8.0/0.04

x = 200

Did you follow?
