Answer:
x = 6
Explanation:
To solve, move all the x’s to one side and all the numbers. Remember when moving numbers to the other side of an equation, the sign changes from either a positive to a negative or vise versa.
9 + 3 = 4/3x + 2/3x
Next, add the like terms.
9+3=12
When adding fractions, add the numerator (top number), but first change denominator (bottom number) if not the same. Here, we don’t need to.
4/3x+2/3x=6/3x
So,
12 = 6/3x
Then, we have to divide each side by 6/3 to make the x alone.
12/6/3 = 6/3x/6/3
To divide with fractions, multiply the reciprocal (opposite number on number line):
12/1·3/6 = x
36/6 = x
6 = x
