First set up the equation to find answer: y=7-x. Then add it to the variable. 3x-1(7-x)=1. So that makes it 3x+-7+-1=1. Add like terms -7+-1=-8, so 3x+-8=1. Now to find x just switch the 8 to the other side. So you end up with 3x=9 since when you take away a number from one side you need to use the opposite value so adding 8 to -8 will cancel it out, then add it to the other, then just divide. 9/3=3, from here just substitute to find y. y=7+3. y=10.
The answer is x=2 and y=5. I hope I helped!
Answer:
B. 12
Step-by-step explanation:
3/4 can be converted to something over 16. You have to multiply 4 x 4 to get to 16, so do the same with 3, and 3 x 4 is 12. Now the fraction/proportion is 12/16, so they will win 12 games.

Answer:
2.29
Step-by-step explanation:
First determine the square root of 17.8
√17.8 = 4.22
second, determine the value of 
= 1.93
subtract 1.93 from 4.22
4.22 - 1.93 = 2.29
