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:

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.
