-8a + 12
The 'x' coordinate of the midpoint is the average of the 'x'
3(-3 + 5x) -1 (4 - 4x)
Simplify each term by first using the distributive property with each set of parenthesis:
3*-3 + 3*5x - 1*4 -1* -4x
Now do the multiplications:
-9 + 15x -4 + 4x
Combine like terms
15x +4x - 9 -4
19x - 13
Wow what grade are you in that seems hella confusing!! I feel bad for you!
