Step-by-step explanation:
The easiest thing to do here is:
4x + 2 = -2 and 4x + 2 = 26
Just know whaever you get for x is greater or less than the actual answer.
4x + 2 = -2
- 2 - 2
4x = -4

x = -1 <--- Because -2 is supposed to be greater than x, x equals any number less than -1 but not -1.
4x + 2 = 26
- 2 - 2
4x = 24

x = 6 <--- Because 26 is supposed to be less than x, x equals any numbey greater than 6 but not 6
Answer:
B) 8,4 pounds
Step-by-step explanation:
![y = 1,8[4] + 1,2; 8,4 = y \\ \: \: \: \: \: \: \: \: \: \: \: 7,2](https://tex.z-dn.net/?f=y%20%3D%201%2C8%5B4%5D%20%2B%201%2C2%3B%208%2C4%20%3D%20y%20%5C%5C%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%20%5C%3A%207%2C2)
You substitute <em>four</em><em> </em><em>weeks</em><em> </em>in for <em>x</em>,<em> </em>multiply that by 1,8 to get 7,2, and finally add 1,2 to it, to get the total weight loss of 8,4 pounds [3,81018 kilograms].

M = 2(x + n)
m/2 = x + n
x = m/2 - n
