Question

If W + 6 = 3 and v-4 = 2, what is the value of w + v?

Answer 1

w = - 3 and v = - 2

Explanation:

Because w + 6 = 3 you would subtract 6 and whatever you do to one side you would do to the other.

w= - 3

Answer 2

`w + v = 3`

Explanation:

Solve for w

`w + 6 = 3`

Move 6 to subtract 3.

`w = 3 - 6 \\ w = - 3`

Solve for v

`v - 4 = 2`

Move 4 to add 2

`v = 4 + 2 \\ v = 6`

Solve for w+v

Substitute w = -3 and v = 6

`w + v = - 3 + 6 \\ w + v = 3`
