Answer:
x=-2, y=-6
Step-by-step explanation:
Simple substitution.
Since y is isolated in one of the equations already, you can plug it into the second equation.
x - 2(3x) = 10
x - 6x = 10
-5x = 10
x = -2
Sub. x = -2 into 3x = y:
3(-2) = y
y = -6
Answer:
Step-by-step explanation:
m (x) = (x+ 5) / (x -1) and n(x) = x - 3.

Hence

but n is a function and n = x-3. Now, replace value of n on m (n)

simplify it

since (m . n) (x) is a fraction function, its domain will be all x such that the denominator is NOT 0. That is

among options, only C has the same denominator with 
Hence their domains are the same.
The answer to this problem is 16/15
$o u solve this by turning 5/8 into 8/5 then turn 6/9 into 2/3 , Then u multiply 2/3 and 8/5 and you get the answer 16/15.
You gotta round the be to 100,000
3(8x - 5) = -4(7 - 6x)
Distribute 3 and -4 inside their respective parentheses.
24x - 15 = -28 + 24x
Add 28 to both sides.
24x + 13 = 24x
Subtract 24x from both sides.
13 = 0
This is an untrue statement, so that means there are no solutions to this equation.
Your answer is no solution.
