Answer:
3( n + )² - = 0
Step-by-step explanation:
3n² = 6 - 17n ⇔ 3n² + 17n - 6 = 0
3( n² + 2 × n + ( )² - ( )² - 2 ) = 0
3( n + )² - 3 × - 6 = 0
3( n + )² - = 0

Answer:
3x-4=107* why vertical angles
Step-by-step explanation:
3x-4=107
add 4 on both sides
3x=111*
x=37
Step-by-step explanation:
8)
describe y in terms of x
y=5+x
so now replace y with terms of x
5+x+3x=37
4x=32
x=8
y=13
9)
do the same here
x=y+1
2y+x=19
2y+y+1=19
3y=18
x=6
y=7
