How do you solve #-1 3 - 7 v = - 5 ( v + 1 )#?

Answer 1

Nathan Axel

#v = -4#

#-13 -7v = -5(v+1)#

#-13 - 7v = -5v-5#

#-7v+5v=-5+13 " "# (add #5v# and #13# to both sides )

#(-7+5)v = -5+13#

#-2v=8#

#2v=-8" "# (multiply or divide both sides by #-1#)

#v = -4" "# (divide both sides by #2#)

To solve the equation (-13 - 7v = -5(v + 1)), first distribute the (-5) on the right side: (-13 - 7v = -5v - 5). Then, combine like terms: (2v = 8). Finally, divide both sides by (2) to solve for (v): (v = 4).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
