Answer:

Step-by-step explanation:

1. 21= 6x+3

2. Subtract the 3 from one side which will cancel it out. Then go to the other side of the equation and subtract 3 from 21. The equation will now look like this- 19= 6x

3. Now divide by 6 on one side to cancel it out. Then go to the other side and divide 19 by 6.

Answer: X = 3.16666666667

Two things to remember when doing these equations

- Think of it as trying to get x by itself

- If you add, subtract, divide, or multiply on one side of the equation always remember to do the same thing to the other side.

Answer:

$10\frac{29}{30}$

Step-by-step explanation:

$5\frac{1}{2} +3\frac{2}{3} +1\frac{4}{5}$

Let us group the integers and the fractions.

$5\frac{1}{2} +3\frac{2}{3} +1\frac{4}{5}$ = $(5+3+1)+(\frac{1}{2} +\frac{2}{3}+\frac{4}{5} )$

= $9+\frac{15+20+24}{30}$

$= 9+\frac{59}{30}$

$=9+1\frac{29}{30}$

$=10\frac{29}{30}$
