If m can be negative, m = -1 would be the answer. Substituting the value of m as -1 into the equation above, we get (7 - 3(-1)) = (7+3) = 10 and ((-1)^2-1)) = 1-1 = 0. Thus, 10/0 = 0.
Answer / Step-By-Step Explanation:
<em>"Twice one number plus a second number is 42."</em>
2x + y = 42
y = -2x + 42
<em>"The first number is 4 more than 3 times the second."</em>
x - y = -6
x - (-2x + 42) = -6
x + 2x - 42 = -6
3x = 36
First number: x = 12
Second Number: y = -2 (12) + 42 = -24 + 42 = 18
2 × 12 + 18 = 42
(24 + 18 = 42)
Hope this helps!
