Answer:
5 and -5
Step-by-step explanation:
Opposite numbers are the same distance from 0 on the number line. So, each of the numbers is a distance from zero that is half the distance between them.
The numbers are 10/2 = 5, and -5.
Two inequalities are equivalent if they have the same set of solutions.
x - 5 ≤ 6 - 5
x - 5 ≤ 1 |add 5 to both sides
x ≤ 6
Answer:
x = 17
Step-by-step explanation:
8x+4=7(x+3) - Equation
8x+4=7x+21 - Distribute the 7
8x-7x=21-4 - Isolate the x
x=17 - Answer
