<span>4x+7=15
First step is to subtract 7 from both sides to get rid of it.
4x + 7 - 7 = 15 - 7
4x = 8
Now all you have to do is divide both sides by 4.
4x/4 = 8/4
x = 2
The answer is x = 2.</span>

The answer is 5 5/6 simplified to the max.
rewrite the equation with separated parts
-3 1/2 - 2 1/3
-3 - 2 = -5
-1/2 - 1/3? u need to find the LEAST common denominator
-3/6 - 2/6 = -5/6
how did I get 6?
Rewriting input as fractions if necessary:
1/2, 1/3
For the denominators (2, 3) the least common multiple (LCM) is 6.
Therefore, the least common denominator (LCD) is 6.
Now lastly combine them total and its -5 - 5/6 = -5 5/6.
