Answer:

$285y = 15\\y = \frac{15}{285}\\y = \frac{1}{19}$

Step-by-step explanation:

You have to divide the entire equation by 285 to get y alone.

Then, simplify the fraction to get 1/19.

What is the solution to this system of linear equations? y − 4x = 7 2y + 4x = 2 (3, 1) (1, 3) (3, −1) (−1, 3)

ohaa [14]

Y - 4x = 7...y = 4x + 7
now sub 4x + 7 in for y in the other equation
2y + 4x = 2
2(4x + 7) + 4x = 2
8x + 14 + 4x = 2
12x = 2 - 14
12x = - 12
x = -1

y - 4x = 7
y - 4(-1) = 7
y + 4 = 7
y = 7 - 4
y = 3

solution is : (-1,3)

Answer:

decrease by 50%

Step-by-step explanation:

$\frac{0.4x}{0.8y} =\frac{x}{2y}$

Decreased by 60% = (100%-60%)x = 0.4x.

Decreased by 20% = (100%-20%)x = 0.8x.

$\frac{x}{y}$ initial fraction, and we can see that denominator will increase 2 times, so fraction will decrease 2 times, or decrease by 50%.
