It’s D
2y-x=6
2(3)-x=6
6-x=6
-x=6-6
-x=0
Divided by- it will not gonna change
2y-x=6
2y-(-2)=6
2y+2=6
2y=6-2
2y/2=4/2
Y=2
Answer:
Step-by-step explanation:
To solve this you take 0 as the starting number, he lost 20 points so you subtract 20 and get -20. Next add 15 points. You then get -5. Then he got another answer right so you add 35 to -5. It the same if you say 35-5. Which gives you 30. So your answer is 30
Answer:x²-2x-8
X²-2x=8
X²= -2x + (-1)² = 8 + (-1)²
X²= -2x + 1 = 8 + 1
X²= -2x + 1 = 9
(X-1)² = 9
√(x-1)² = √9
X-1 = ± 3
X= 1 + 3= 4
X= 1 - 3= -2
X= 4 or X= -2
Step-by-step explanation:
7(5 + x) = -14
7 x 5 = 35
So 35+7x=-14 divide through by 7 first
5+x=-2
X=-7
