Step-by-step explanation:
You first have to distribute correctly so it simplifies is 15+3n
Answer:
x = -2, y = -3
Step-by-step explanation:
y - 3x = 3
x - 2y = 4
-3x + y = 3
x - 2y = 4
-6x + 2y = 6
x - 2y = 4
Add the equations.
-5x = 10
x = -2
Substitute -2 for x in the first original equation and solve for y.
y - 3x = 3
y - 3(-2) = 3
y + 6 = 3
y = -3
Answer: x = -2, y = -3
You should use 22/7 when you are dealing with other fractions.
The answer is 14.
a number divided by 1/2 will equal that number times 2
7*2 = 14
