Answer: y=-2x-9
Step-by-step explanation:
Add 4x to both sides because the slope (-2x) needs to be on the same side as the y-intercept (-9). Then divide everything by 2 to get your answer because you want to get y by itself, since there is two of them. 2y-4x=-18 becomes y=-2x-9.

Answer:
3ax-by+c
Step-by-step explanation:
Step1: Collect all the like terms
Like terms are similar variables, for example;
- (ax, 2ax) are all like terms since they have a common variable (ax)
- (by, -3by,by) are also like terms since they have a common variable (by)
- (c, c, -c) are also like terms since they have a common variable (c)
Step 2: Sum of all the groups of like terms
(ax+2ax)+(by-3by+by)+(c+c-c)=3ax-by+c
The answer is 3ax-by+c
