Please give detail in what your trying to answer so I can answer it for you
3.6 (5 x 4) ÷ 3 + 5.0
use the PEMDAS rule
P - parentheses
E - exponents
M - multiplication
D - division
A - addition
S - subtraction
3.6 (5 x 4) ÷ 3 + 5.0
= 3.6 (20) ÷ 3 + 5.0
= 72 ÷ 3 + 5.0
= 24 + 5.0
=29
so the final answer would be 29!!
2x+1=4x+6
-2x -2x
1=2x+6
-6 -6
-5=2x
/2. /2
-2.5=x
(This kind of equation?)
I hope this helps you
