Hello, and welcome to Brainly!
It seems y ou want to find the value of x in the expression -4x + 7 - 6 = 22.
If that's the case, combine the 7 and -6, obtaining: -4x + 1 = 22. We want to isolate x. To achieve this, subtract 1 from both sides, obtaining -4x = 21.
Dividing both sides of this equation by -4 gives us x = (-21)/4.
This is the "solution" of the given equation.
Answer:
D) 675 units per day.
Step-by-step explanation:
We can write a function to model the situation.
The company is currently producing 275 units per day.
And it will increase its production by 50 units after each year.
Therefore, after <em>y</em> years, its production in units per day will be:

Explicación paso a paso:
Para el celular:
Número total de teléfonos móviles registrados antes del terremoto = 1354 teléfonos móviles
Número total de teléfonos móviles registrados después del terremoto = 571+ 28 = 599 teléfonos móviles
<em>Número total de teléfonos móviles en el almacén después del terremoto = 1354 + 599 = 1953 teléfonos móviles.
</em>

</em>
Para la tableta:
Número total de tabletas registradas antes del terremoto = 1586 teléfonos móviles
Número total de tabletas registradas después del terremoto = 942 + 45 = 987 teléfonos móviles
<em>Número total de tabletas en el almacén después del terremoto = 1586 + 987 = 2573 tabletas.</em>
