I can help you set up the equation, if you don't actually practice isolating you're never gonna learn,
it says the /sum of a number and seven/ which means n+7
is equal to /five less than the number/ so n-5
so your two parts are
n+7 = n-5

Answer:
$17.28 Amalie paid for the shirt.
Step-by-step explanation:
Amalie makes a profit of 20%, She sells a shirt for $21.60.
Here,
21.6 × 20/100 = $4.32
Now,
$21.60 - $4.32 = $17.28
Thus, $17.28 Amalie paid for the shirt.

Answer:
They have the same y-intercept of -6.
Answer:
Step-by-step explanation:
Parallel lines share the same slope.
In the given 4x - 2y = 4, the first 4 (the coefficient of x) and the -2 (the coefficient of y) determine the slope; all lines parallel to 4x - 2y = 4 have equations which are identical to 4x - 2y = 4 EXCEPT that their constants (in this case 4) differ.
4x - 2y = 0
4x - 2y = -3
4x - 2y = 7
constitute a set of parallel lines.
If we reduce 4x - 2y = 4 to 2x - y = 2, the second equation has the same slope AND same y-intercept as does the first.
