60. W+4 = 7w given
V=w given
Step #1: Be sure to put all your given statements down.
Notice that what you need to prove and one of your given statements give you a hint as to what you need to do next.
Step #2: Start solving the first given statement for w..

61. w +4 -4 = 7w -2 -4 subtraction property of equality
W+4 = 7w given
V=w given
w = 7w subtraction property of equality
Step #1: Be sure to put all your given statements down.
Step #2: Start solving the first given statement for w.
There are a few ways to do this.
Subtract 4 from both sides

62. w = 7w -6 subtraction property of equality
W+4 = 7w given
V=w given
w = 7w subtraction property of equality
-6w = subtraction property of equality
Step #1: Be sure to put all your given statements down.
Step #2: Start solving the first given statement for w.
There are a few ways to do this.
Subtract 4 from both sides
Step #3: isolate the unknown by subtracting 7w

63. w = 7w -6 subtraction property of equality
W+4 = 7w given
V=w given
w = 7w subtraction property of equality
-6w = subtraction property of equality
W=1 division prop. Of equality
Step #1: Be sure to put all your given statements down.
Step #2: Start solving the first given statement for w.
There are a few ways to do this.
Subtract 4 from both sides
Step #3: isolate the unknown by subtracting 7w
Step #4 divide by -6 to isolate w.

64. w = 7w -6 subtraction property of equality
W+4 = 7w given
V=w given
w = 7w subtraction property of equality
-6w = subtraction property of equality
W=1 division prop. Of equality
V=1
Transitive property of equality (2,5)
Step #1: Be sure to put all your given statements down.
Step #2: Start solving the first given statement for w.
There are a few ways to do this.
Subtract 4 from both sides
Step #3: isolate the unknown by subtracting 7w
Step #4 divide by -6 to isolate w.
Step #5: since v=w and w=1 we can say that v=1
