Question

Number 20 please i’m super stuck and please explain how u got ur answer

Answer 1

z > -9

Explanation:

18 - 5z +6z > 3 + 6

Move the 18 from the left side to the right side by subtracting. So you subtract 18 from both sides. The one on the left cancels out.

-5z + 6z > 3 + 6 - 18

Combine like terms.

-5 + 6 = 1 ; 3 + 6 - 18 = -9

You will be left with 1 z.

z > -9

Answer 2

z>-9

Explanation:

18-5z+6z>3+6

18+z>9

z>-9

add 6z to -5z, add 3 and 6, subtract 18 from both sides, z>-9
