ANSWER

EXPLANATION
We want to find the value of a for which the binomial, 2a-1 is smaller than the value of the binomial 7-1.2a by 7.
This means that, when we subtract 2a-1 from 7-1.2a, we should get 7.

Group similar terms:


Divide both sides by -3.2,


X = 3,6 : 6 = 0,6
x : 2x : 3x
0,6 : 1,2 : 1,8
3/8+5/16
=3/8+5/16
=6/16+5/16
=6+5/16
=11/16
