Answer:
Step-by-step explanation:
Ok let's make an equation in terms of a
Just by rearranging
a=(Z/18b)+6b
(-8x - 12) + (9x + 4)= x-8
(-3p^3 + 5p^2 - 2p) + (3r^2 - 3r)= -3p^3+5p^2-2p+3r^2-3r
( -3p^3 + 5p^2 - 2p) + (-p^3 - 8p^2 -15p)= -4p^3-3p^2-17p
. ( 9r^2+4r-7) + (3r^2-3r)= 12r^2+r-7
Please refer to the picture above.
