Step-by-step explanation:
-3x - 7y = -63
-(3x + 7y) = -63
3x + 7y = -63/-1
3x + 7y = 63
Value of x
3x + 7y = 63
3x = 63 - 7y
x = (63 - 7y)/3
Value of y
3x + 7y = 63
7y = 63 - 3x
y = (63 - 3x)/7
(3n-4)=3(n+4)
3n-4=3n+12
no solution
There wouldn’t be a solution to this equation because the n cancels out when you subtract 3n-3n.
Question 2 the answer is 4
Answer: positive
The absolute value of every nonzero integer is a positive integer.
Examples are
|-2| = 2
|7| = 7
The absolute value represents distance which can never be negative. Negative distance does not make sense.
Answer: the number is 3.
Step-by-step explanation:
(x × 10) + 6 = 36
[(3) × 10] + 6 = 36
