Answer:
1. Add 6 to both sides, cause that is the inverse of subtraction, so you get 5x = 50 as 6 cancels 6 out.
2. Divide 5 from both sides and get x = 10
19 has 2 factors (1,19)
21 has 4 factors (1,3,7,21)
23 has 2 factors (1,23)
25 has 3 factors (1,5,25)
you need the nearest number 25 that has 5 factors or more :28(1,2,4,7,14,28)
Answer:

It should be B I’m pretty sure
Answer:
x=0 , y=0
Step-by-step explanation:
2x +6y= 8 .....eqn 1
4x +12y= 16....eqn2
we multiply eqn 1 by 2.. because we want at least one variable to have the same coefficient so we can simply.
2x +6y =8... ×2
will give you 4x +12y = 16....eqn 3
so now we subtract eqn 2 from eqn 3
4x + 12y= 16
- 4x + 12y = 16
_____________
0 + 0 = 0
therefore x = 0 and y= 0
