Answer:
x = -9, y = -3.
As an ordered pair it is (-9, -3).
Step-by-step explanation:
Substitute x = 3y in equation 1:
2y + 3y = -15
5y = -15
y = -15/5
y = -3.
Now find x by plugging y = -3 in x = 3y:
x = 3*-3 = -9.
Check the answer in equation 1:
2(-3) + -9
= -6 - 9
= -15 Correct.
<span>The answer is 7.0. When you want to round to the nearest tenth, you need to leave only one decimal. The second decimal is 5. So, the first decimal will be rounded to the first bigger number. In this case 6.95, the first decimal number 9 will increase to 10 which means that the number 6.95 will be rounded to a whole number: 6.95 = 7.0</span>
