Answer:
y = 2
x = 5
Step-by-step explanation:
4x + 5y = 10 | ×3 |
3x - 3y = 21 | ×4 |
12x + 15y = 30
12x - 12y = 84
____________--
27y = -54
y = -54/27
y = 2
4x + 5y = 10 | ×3 |
3x - 3y = 21 | ×5 |
12x + 15y = 30
15x - 15y = 105
____________+
27x = 135
x = 135/27
x = 5

We are given:
12 counters which are three-fourths of a set of counters, meaning the total number of counters in a set is determined by:
total number of counters in a set = 12/(3/4) = 16 counters
Therefore, we need to draw 16 counters and shade 12 of them to represent the three-fourths of the set.
