Answer:
Substitute, <em><u>y = -3</u></em> and <em><u>x = k</u></em> on the equation.
=> k - 2×(-3) = -2
=> k = -2 + (-6)
=> k = - 8

Answer:
Sarah would peel 3 oranges in 15 minutes
Explanation:
I’m not sure if I did it right but i multiplied 7 by 60 (hours by minutes in an hour) and got 420. Then I divided it by 15 and got 28. Finally, I divided 84 by 28 and I got 3. I don’t if I am late or right for this question though.
9m-28=2m
9m-28-2m=2m-2m
(9m-2m)-28=0
7m-28=0
7m-28+28=0+28
7m=28
(7m)/7 = 28/7
m=4
Answer: we multiply the second equation by -2. This property is the multiplication property of equality (1).
Then, we add the two equations generated. (2) addition property of inequality.
Next, we divide both sides of the equation by 13. That is division property of inequality.
Moreover, we substitute the value obtained for y in the first equation. This is substitution property of equality.
Then, we simplify
Next, we add +3 to both sides of the equation in order to have an equation with only one side having a variable. That is addition property of equality.
Lastly, we divide both sides of the equation by 4. This is division property of equality.
