I got it wrong anyone know the answer thank u!

Choice 4 (s - 3 = 12)

Step-by-step explanation:

I think you made a reading error on this question, as it said "for which equation is s = 9 not the solution?" No need to fret though, this can easily be solved by substituting 9 into the variable s of each equation.

1. We know it's not choice 1 (s + 6 = 15), because doing 9 + 6 does equal 15.

2. We know it's not choice 2 (7 + s = 19), because doing 7 + 9 does equal 16.

3. We know it's not choice 3 (13 - s = 4), because doing 13 - 9 does equal 4.

4. Choice 4 (s - 3 = 12) is the correct answer because doing 9 - 3 equals 6, not 12. Thus this equation is incorrect, meaning this is the correct choice.

Choice 4/D is the correct choice.

The answer is D s-3=12 because s=9 and 9-3=6.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
