Question

Sole the following equation -3=z+4

Answer 1

Explanation:

solution z = -7

-3=z+4

-3 -4 = Z + 4 -4

-3 -4 = z + 4 - 4

-7 = z + 4 - 4

-7 = z + 4-4

-7 = z

-7 = z

z=-7

solution z = -7

Answer 2

Hello!

Let's solve this equation for z.

In order to do that, simply add 3 to both sides:

0=z+7

Move z to the left:

-z=7

Divide both sides by -1 in order to remove the minus next to z:

z=-7 (answer)

Hope everything is clear.
