Question

what is the solution of this equation?
-7 + 1/2z = -4 explain.

Answer 1

its one half not a division sign

Answer 2

Haha ok :)

Answer 3

Let's see, so -7+1/2z=-4
Add 7 to both sides, first off, so that we can get the variable on one side.

Answer 4

So you have 1/2z=3

Answer 5

*would

Answer 6

hold on i need paper

Answer 7

Ok :P

Answer 8

1/2z = -4 +7
1/2z = 3
z = 2 * 3
z = 6

Answer 9

how do i know that 1/2 = 3???

Answer 10

Well, when you added 7 to each side you got 1/2z=3
Then you would need to dived each side by the reciprocal of 1/2, which is 2

So you would have z=2(3) Z=6 :)

Does that make sense?
