X - y = 3
6x + 4y = 13
x = y + 3
6(y + 3) + 4y = 13
6y + 18 + 4y = 13
10y = 13 - 18
10y = - 5
y = - 5/10
y = - 1/2
x = - 1/2 + 3
x = - 1/2 + 6/2
x = 5/2
Answer:
15
Step-by-step explanation:
| −5 −2(5)|
Since absolute value is positive that would be
5 + 10 = 15
Here's another way of looking at it:
| −5 − 10| Subtract 10 from -5
| −15| since absolute value is positive, the answer is 15

Answer:
A = π(7x + 3)² cm²
Step-by-step explanation:
A = πr² is the appropriate equation. If r = 7x + 3 cm, then the area of this particular circle is:
A = π(7x + 3)² cm²
