You have to use a system. the first would be x + y = 12 since she has 12 coins. the other equation would be 0.05x + 0.1y = 0.95 (an easier way is 5x + 10y = 95 if you clear it). now you just solve using substitution or elimination.
Answer:

Step-by-step explanation:
Notice how it passed through at exactly (3,2) and (6,4).
By taking the formula for slope:

Substituting this into the slope-intercept form
y = mx + b
where m is the slope of the line and b is the y-intercept.
Since we were not given the y-intercept and the line started or passes through (0,0), we can safely assume that b = 0.
Therefore,
