Integers consists of zero (0), the positive natural numbers (1, 2, 3, ...), also called whole numbers or counting numbers, and their additive inverses (the negative integers, i.e., −1, −2, −3, ...).
So they are just asking for what positive or negative numbers make the equations true.
So remember how positive and a negative numbers relate and you will be fine.
B. x-(+7)=x+(-7)
C. X-(-25)=x+25
A. X-(-3)=x+3
Answer:
<h3> A: One</h3><h3> B: x = 4 </h3>
Step-by-step explanation:
3(2x - 7) = 3
÷3 ÷3
2x - 7 = 1
+7 +7
2x = 8
÷2 ÷2
x = 4
