Answer:
3
Step-by-step explanation:2-5
7m+2=7n−5
Swap sides so that all variable terms are on the left hand side.
7n−5=7m+2
Add 5 to both sides.
7n=7m+2+5
Add 2 and 5 to get 7.
7n=7m+7
Divide both sides by 7.
7
7n
=
7
7m+7
Dividing by 7 undoes the multiplication by 7.
n=
7
7m+7
Divide 7+7m by 7.
n=m+1
-25(x-4)=-55(x-10)
-25x+100 = 55x-550 |+25x
100 = 80x-550 |+550
650 = 80x | /80
65/8 = x
x = 8 1/8

26= 8+v
You need to get V (the variable) by itself so in order to do this you need to remove 8 from the equation. So to do this, subtract 8 from the right side and subtract it from the left as well. Whatever you do to one side you do to the other.
26=8+v
-8 -8
18=v
You are left with v=18
