Ответ:
x= -5; y=6
Step-by-step explanation:
−3x − 5y = −15
−3x − 3y = −3 .(-1)
−3x − 5y = −15
+3x +3y = +3
0 - 2y = -12
y = - 12
-2
y=6
−3x − 3y = −3
- 3x -3.6 = -3
-3x -18 = -3
-3x = 18-3
x= 15
-3
x= -5

Explained.
Step-by-step explanation: We are given to explain the meaning of the following statement:
"Everyone has a financial plan but not everyone has a financial goal."
From the above statement, we mean that we always plan our future financially and verbally but we not all of us do everything possible to make the plan work. That is planning is a one thing but doing something to make the plan work is completely different.
Hence explained.
