7.6 - 5(k + 1.1) = 1.6
7.6 - 5(k + 1.1) - 7.6 = 1.6 - 7.6
-5(k +1.1) = -6
-5(k + 1.1) -6
-------------- = ---------
-5 -5
k + 1.1 = 6
-----
5
k + 1.1 - 1.1 = 6
----- - 1.1
5
k = 0.1
4/5x - 4/10 = 2/20...multiply everything by common denominator 20
16x - 8 = 2
16x = 2 + 8
16x = 10
x = 10/16 which reduces to 5/8 <=
