Isolate C, by multiplying both sides by -10, because the opposite of dividing by -10 is multiplying by it
so C=-8(-10)
the answer is C=80, positive because a negative multiplied by a negative is equal to a positive
-2x + 6 + 6x = 6 (2x - 3) <em>this is the equation</em>
-2x + 6 + 6x = 12x - 18 <em>distributive property has been applied</em>
4x + 6 = 12x - 18 <em>like terms have been added</em>
6 = 8x -18 <em>4x has been</em><em> </em><em>subtracted from both sides</em>
24 = 8x <em>-18 has been added to both sides</em>
3 = x <em>8 has been divided from both sides</em>

I hope this helps! Let me know if I need to explain more or if I got something wrong. Have a nice day!
Answer:
a) 23.0769% increase
b) 9.375% decrease
Step-by-step explanation:
Answer:
x=3 and y=3
Step-by-step explanation:
explanation for x
using distributive property, 3(2x+10) should be 6x + 30 because you need to multiply both inside numbers by the outside number.
Next, you need to isolate the variable so the 12 is suptracted from thirty which leaves you 6x+18 and 12x. Since six is half of twelve, six is half of the other side, and then there is 18 which is the other six, so that means 6x=18, so simplifies, x=3 because 6×3=18
explanation for y
2(2y-3) using the distributive property, should be 4y-6. Take the 12 from 2y+12 and subtract six from it and you get 2y+6 and 4y. So, since 2y plus 6 equals 4y, 2y is half of 4y and then there is a plus six, which equals the other half, so 2y=6, and simplified, y=3
