Answer:
3x - 8 > 22
Step-by-step explanation:
" eight less" means to subract 8 form something. If you had 10 apples and I took some so now you had 8 less apples, you'd have 10 - 8 = 2 apples
"three times a number" means 3x. 3 times some number.
The expression 3x - 8 means "8 less than 3 times a number"
"is" is math is a statement of equality, either an equals sign or an inequality needs to go here.
Our inequality is
3x - 8 > 22

Answer:
m=31/2, n=-24. (31/2, -24).
Step-by-step explanation:
2m+n=7
4m+3n=-10
-------------------
n=7-2m
4m+3(7-2m)=-10
4m+21-6m=-10
-2m=-10-21
-2m=-31
2m=31
m=31/2
2(31/2)+n=7
31+n=7
n=7-31
n=-24
