Final answer:
To find the value of x, set m29 and m27 equal to each other and solve for x.
Step-by-step explanation:
To find the value of x, we need to solve for x in the given equations. First, we can set m29 and m27 equal to each other:
2x + 3 = 3x - 9
Now, we can solve for x:
3x - 2x = 9 + 3
x = 12
So, the value of x is 12.
