Answer:
x is 48 y is 12 z=50
Step-by-step explanation:
x+y+z=110
x=4y
4y+2=z
4y+y+4y+2=110
9y+2=110
9y=108
y=12
x=48
z=50
Hope this helps!
I think it’s the first one
Sorry if I’m wrong
3x+1/10=x-1/7
subtract 1/10 from both sides
3x=-1/7-1/10+x
subtract x from both sides
2x=-1/7-1/10
add -1/7 and -1/0
1/7=10/70
1/10=7/70
-10/70-7/70=-17/70
2x=-17/70
divide by 2 ro multiply by 1/2
x=-17/140
