Ryan,

  In 3x + -5.44=29 we want to find the value of x.  The two operators + - together are not quite proper notation but I believe the equation should be 3x + (-5.44)=29 or more simply 3x  -5.44=29.

1st:  3x -5.44=29   on both sides of the = sign, add +5.44 and get:

3x -5.44 + 5.44 =29 +5.44    or   3x = 34.44

2nd:  Divide both sides of the equation by 3 and get:

3x /3 = 34.44 /3    or   x=  11.48

3rd:  Since we are dealing with no more that 3 significant digits, the answer is reduced to:

x=11.5

Good Luck!   BruceS

3x + -5.44=29

The "+ -" can be reduced to -:

3x - 5.44=29

Now, we add 5.44 to both sides:

3x - 5.44+5.44 = 29+5.44

3x = 34.44

Finally, we divide both sides by 3:

3x/3 = 34.44/3

x = 11.48

3x+ -5.44=29

So, a positive sign and a negative sign make the sign negative so rewrite the problem as

 

3x-5.44=29

 

then, move 5.44 to the other side of the problem to get 3x alone. To to this, ADD 5.44 to both sides. This will cancel out the -5.44 on the left because -5.44+5.44=0

 

So the problem now looks like this: 3x=29+5.44

Add 29 and 5.44 which gives you 3x=34.44

Then, divide both sides by 3 and this will tell you what x is equal to.

3 divided by 3 is one. So the right side of the problem is 1x or just x. 34.44 divided by 3 is 11.48.

 

So, 1x or x (it is the same thing) is equal to 11.48.

 

I hope this helped :)

3x + -5.44 = 29

First, you want to add the inverse of -5.44 to both sides of the equation.

3x=29 + 5.44

3x = 34.44

Now you want to multiply the invers of 3 (which is 1/3) to both sides of equation. 3 x 1/3=1, so that leaves you with just x on one side.

x = 34.44/3

x = 11.48
