Just change the numbers
For what values of a is the value of the binomial 2a−1 smaller than the value of the binomial 7−1.2a by 7?

a=0.3125
work:
7-1.2a-(2a-1)=7
a=0.3125
work:
7-1.2a-(2a-1)=7
a=0.3125
(7-1.2a)=(2a-1)+7
8-3.2a=7
-3.2a=-1
3.2a=1
a=1/3.2
a=10/32
a=5/16
8-3.2a=7
-3.2a=-1
3.2a=1
a=1/3.2
a=10/32
a=5/16
