Subtract 2 from both sides
-2u = -7u + 17 - 2
Simplify -7u + 17 - 2 to -7u + 15
-2u = -7u + 15
Add 7u to both sides
-2u + 7u = 15
Simplify -2u + 7u to 5u
5u = 15
Divide both sides by 5
u = 15/5
Simplify 15/5 to 3
u = 3
2x+15 = 3x-25
2x-3x = -25 -15
-x = -40
x = 40
It is 780.99999 sorry if i'm incorrect
Answer:
51.2%
Step-by-step explanation:
Answer:
x = 7.5
Step-by-step explanation:
Since we see that sides AD and DC are equal, as well as sides BE and EC, we can use this information to conclude that the value of 2x-7 is equal to double the value of DE.
2x - 7 = 4(2)
2x - 7 = 8
2x - 7 + 7 = 8 + 7
2x = 15
x = 7.5
