Answer:
Fraction: 1/ 5 n= 7
Step-by-step explanation:
To find n first you cross multiply : 2/ 10 * n / 35
= So we multiply 10 and n ( answer = 10n)
= Then 2 and 35 ( multiply) ( answer = 70)
Now algebra
70 = 10n
Divide both sides by 10
10n / 10 = 70 / 10
n = 7
The fraction becomes 7 / 35
When this is simplified the answer is 1 / 5
To simplify you divide the numerator and denominator of the fraction by 25 ( GCF )

Answer:
(x, y) = (5, 4)
Step-by-step explanation:
Subtracting the second equation from the first eliminates the x term.
(4x +6y) -(4x +2y) = (44) -(28)
4y = 16 . . . . simplify
y = 4
Using the second equation to find x, we have ...
4x +2(4) = 28
x + 2 = 7 . . . . . . divide by 4
x = 5 . . . . . . . . . subtract 2
The solution is (x, y) = (5, 4).
