Answer:
m = -4
*Pick the option-> (m) is negative
Step-by-step explanation:
Solve this equation with inverse operations;
Let x represent the # of 2-hour days and y the # of 3-hour days. Jimmy's study was spread over 10 days. Thus, x + y must sum up to 10. Also, 2x + 3y must sum up to 22 hours.Our system now looks like this:
x + y = 10
2x + 3y = 22
Multiply the first equation by -2: -2x - 2y = -20 Add the 2nd equation to this:
-2x - 2y = -20
2x + 3y = 22
------------------ y = 2 So Jimmy had 2 3-hour study days and 8 2-hour study days.
Note how these figures add up to 22: 6 + 16 = 22

Answer:
x = 1 (Option C)
Step-by-step explanation:
3x - 4y = -5 (1)
-3x - 4y = -11 (2)
On adding
3x - 4y - 3x - 4y = -11 + 5
6x = 6
x = 6/6
x = 1
