In algebra, combine your like variables then solve for the equation. I always tell my students that your goal is to get letters on one side and numbers on the other.
So,
8.3x - 4.7 + 2.9x = 47.94
combine like variables
(8.3x + 2.9x) - 4.7 = 47.94
11.2x - 4.7 = 47.94
You then want to move 4.7 to the next side by adding it to both sides:
11.2x = 47.94 + 4.7
11.2x = 52.64
Now just divide both sides by 11.2
x = 52.64/11.2
x = 4.7

8.3x-4.7+2.9x=47.94
add like pairs
10.11x-4.7=47.94
add 4.7 to both sides
10.11x=52.64
divide everything by 10.11
x=4.7

ok..the given equation is
8.3x-4.7+2.9x=47.94
8.3x+2.9x=47.94+4.7
8.3x+2.9x=52.6
11.2x =52.64
x=(52.64)/(11.2)
x =4.7
hope dis helps......

8.3x +2.9x= 47.94 +4.7
11.2x= 48.64. x= 48.64/11.2. = 12.16/2.8= 3.04/ 0.7.
x=4.34.

5.4x = 52.64
. .
x = 9.7481
* the dots above are to show its recurring, i.e 3.4444444444
could just be written as 3.4 with a dot above the 4.
