The correct question is:
Using the digits 1 to 9 at most one time each place a digit in each box to create an equation where x is a negative value solve your equation to prove your answer.
__x + __ = __
Answer:
1. 9x + 8 = 1
2. 7x + 6 = 2
3. 5x + 4 = 3
Step-by-step explanation:
1. 9x + 8 = 1
Subtract 8 from both sides
9x = 1 - 8
9x = -7
Divide both sides by 9
x = -7/9
2. 7x + 6 = 2
Subtract 6 from both sides
7x = 2 - 6
7x = -4
Divide both sides by 7
x = -4/7
3. 5x + 4 = 3
Subtract 4 from both sides
5x = 3 - 4
5x = -1
Divide both sides by 5
x = -1/5
Answer:
The solution set of equations assuming x as a negative value can go from:
x + 9 = 2, that gives us the least possible negative value of - 7 to:
x + 3 = 2, that gives us the highest negative value of - 1 to x
The only condition is that the second term of the equation should be a higher number than the result.
Step-by-step explanation:
If x is a negative value, let's create the set of equations using digits from 1 to 9 one time, this way:
a. x + 9 = 2
x = 2 - 9
x = -7
b. x + 9 = 3
x = 3 - 9
x = - 6
c. x + 3 = 2
x = 2 - 3
x = -1
d. x + 4 = 2
x = 2 - 4
x = -2
e. x + 6 = 5
x = 5 - 6
x = -1
