Which value is a solution of the equation 5 - 4x = -3?

1 answer:

3 0

Well I don't know, and you forgot to give me any choices or suggestions.
So I'll have to calculate it. You can watch if you feel like it.

You said 5 - 4x = -3

Subtract 5 from each side: - 4x = -8

Divide each side by -4 : x = 2

Answer:

$3 \: s$

Step-by-step explanation:

$y = - 16 {x}^{2} + 32x + 48 \\ 0 = \frac{ - 16 {x}^{2} + 32x + 48 }{ - 16} \\0 = {x}^{2} - 2x - 3 \\ 0= {x}^{2} - 3x + x - 3 \\ 0= x(x - 3) + 1(x - 3) \\0 = (x + 1)(x - 3) \\ \\ x + 1 = 0 \\ x = - 1 \\ x - 3 = 0 \\ x = 3$
