Answer:
x≤24
Step-by-step explanation:
4(x+5)≤116
x+5≤29
x≤29-5
x≤24
1. x-2(2x-3.5)=-14
x-4x+7=-14
-3x=-21
x=7
2. y=2(7)-3.5
y=14-3.5
y=10.5
hope this helps!
Answer:
Solution:
, 3.5, -15, 5
Not a solution: 129 and 
Step-by-step explanation:
20 ≥ 5 + 3x
3x + 5 ≤ 20
3x ≤ 20 - 5
3x ≤ 15
x ≤ 5
x must be LESS than or EQUAL to 5
The

row is filled by just plugging in the corresponding values of

and

into the ODE.
For example, when

and

, you have

and so on.
Equivalent systems = same line = infinite solutions
