Answer:
b= 4
Step-by-step explanation:
b-1.6= 2.4
I would add 1.6 to both sides so that b could be on one side. The opposite of -1.6 is 1.6, so b-1.6+ 1.6= 2.4
b= 2.4+ 1.6
Since -1.6+1.6 cancel out, I get b= 2.4+1.6. I add 2.4+ 1.6 to get 4.
b=4
So, b= 4
To check my work I would plug in b back into the equation:
So...
b=4
b-1.6= 2.4
4-1.6= 2.4
