I need help with this question, I will post it as a photo, please help.

Answer 1

We need to simplify the next given expression:

$7m+\frac{5}{12}+8z+\frac{4}{12}+8m-3z$

We need to solve the like terms, "like terms" are terms whose variables and exponents are the same

Therefore, the like terms are:

7m and 8m

8z and -3z

5/12 and 4/12

Organize the expression:

$7m+8m+\frac{5}{12}+\frac{4}{12}+8x-3z$

Solving the like terms:

$15m+\frac{9}{12}+5z$

Finally, we can simplify the fraction 9/12 by 3/4 because 3*3 = 9 and

3*4 = 12

Then:

$15m+\frac{3}{4}+5z$
