Answer:
Step-by-step explanation:
X={0,12,23}
Y={3,12,15}
X \ Y = { 0 , 23}

Step-by-step explanation:
Answer:
x=8
Step-by-step explanation:
2x-6+4=14
Combine like terms
2x-2=14
Add 2
2x=16
Divide
x=8
Checking work)
2(8)-2=14
16-2=14
14=14
Remember you can do anything to an equation as long as you do it to both sides
17-9x=-3+16x
add 9x to both sides
17=-3+25x
add 3 to both sides
20=25x
divide both sides by 25
