Answer:
c
Step-by-step explanation:
when there is subtraction you add the number with the variable on each side to get it by it's self
+515=y-5+5
20=y
Answer:
All real numbers of x.
Step-by-step explanation:
5x+10=5(x+2) have the exact same equations on both sides.
5x+10=5x+10
If both are graphed, they will intersect each other for every value of x.
-8x - 4y = -20...divide by -4
2x - y = 5...rearrange
2x - 5 = y
this is the same as the other equation...this means they are the same line with infinite solutions
1699 x 8
and that will be your answer
