When simplifying an expression using the properties of operations, you can combine like terms. In this case, the like terms are 4x and 8x.
To combine these terms, you add their coefficients:
4x + 8x = 12x
So, 4x + 8x simplifies to 12x.

Simplify 9g−7h−6g + 2h . (1 point)
To simplify the expression 9g - 7h - 6g + 2h, we combine the like terms:
Combining the g terms, we have 9g - 6g = 3g.
Combining the h terms, we have -7h + 2h = -5h.
Therefore, the simplified expression is 3g - 5h.
Combining the g terms, we have 9g - 6g = 3g.
Combining the h terms, we have -7h + 2h = -5h.
Therefore, the simplified expression is 3g - 5h.

Simplify 6/7c − 5/9d − 1/2 c + 1/3d. (1 point)
To simplify 6/7c - 5/9d - 1/2c + 1/3d, we need to combine like terms.
Combining the c terms, we have 6/7c - 1/2c. To do this, we need a common denominator, which is 14. So we rewrite the fractions as: (12/14)c - (7/14)c = 5/14c.
Combining the d terms, we have -5/9d + 1/3d. To do this, we need a common denominator, which is 9. So we rewrite the fractions as: (-15/45)d + (15/45)d = 0d. The d terms cancel each other out.
Combining the fractions, we have 5/14c + 0d.
Therefore, the simplified expression is 5/14c.
Combining the c terms, we have 6/7c - 1/2c. To do this, we need a common denominator, which is 14. So we rewrite the fractions as: (12/14)c - (7/14)c = 5/14c.
Combining the d terms, we have -5/9d + 1/3d. To do this, we need a common denominator, which is 9. So we rewrite the fractions as: (-15/45)d + (15/45)d = 0d. The d terms cancel each other out.
Combining the fractions, we have 5/14c + 0d.
Therefore, the simplified expression is 5/14c.
