x=−2 and y=−4
If you need explanation Just ask!
Yes, that is correct because if you want to reduce it you divide 8 by 2 and 10 by 2 and you get 4/5
Answer:
Begin by factoring 2 out of 2x^2 - 2x - 12 equals 0:
2(x^2 - x - 6) = 0
2(x - 3)(x + 2) = 0. 2 is never zero, but x-3 and x+2 can each be set = to 0:
This results in x = 3 and x = -2. The equation is true for these two x-values.

What are the numbers of the shades spider eyes and the total
Answer:
x = 5
y = -2
Explanation:
2x + y = 8
y= x - 7
<u>We need are solving for x, and we know what y is</u>
<em><u>We need to substitute the y equation for y in the first equation</u></em>
2x+x-7=8
Step 1: Simplify both sides of the equation.
2x+x−7=8
2x+x+−7=8
(2x+x)+(−7)=8(Combine Like Terms)
3x+−7=8
3x−7=8
Step 2: Add 7 to both sides.
3x−7+7=8+7
3x=15
Step 3: Divide both sides by 3.
3x / 3 = 15 / 3
x = 5
<u><em>Solve for y</em></u>
2x + y = 8
2 * 5 + y = 8
Step 1: Simplify both sides of the equation.
(2)(5)+y=8
10+y=8
y+10=8
Step 2: Subtract 10 from both sides.
y+10−10=8−10
y=−2
