Ответ:
x = 18
Step-by-step explanation:
2x + 5 + 17 = 3x + 4
2x + 22 = 3x + 4
2x + 22 - 22 = 3x + 4 - 22
2x = 3x - 18
2x - 3x = 3x - 18 - 3x
-x = -18
-x / -1 = -18 / -1
x = 18
Hope this helps!
Ответ:
-x + 1 > 3, and 4x + 6 < -2
Step-by-step explanation:
The inequality reads x < -2, so the arrow follows any values that are less than -2. So we need to simplify each inequality in the following options to see which match x < -2.
-4x+3> -5 simplifies to x < 2 so it's wrong
-2x + 4 > -4 simplifies to x < 4 so it's wrong
-x + 1 > 3 simplifies to x < -2, so it's right
2x + 5 < -3 simplifies to x < -4, so it's wrong
4x+ 6 < -2 simplifies to x < -2, so it's right
