II. Find the solution / solution set in each equation / inequality : (3 pts each) 21. x +. 13 = 28
22. x - 10 = 24
23. 2x = 40
24. x + 8 > - 12
25. 3 x 4 < 8​

Now ,

No 1). x + 13 =28
X = 28-13
Therefore x = 15 ans

No 2). X - 10 = 24

X = 24 + 10
Therefore x = 34 ans

No 3). 2x = 40
X =40/2
Therefore x = 20 ans

No 4). X+8 > -12
X > -12-8
Therefore X > -20 ans
Inequality={-19,-18,-17}

No 5). Plz right it clearly i don’t understand the sign is Multiply or X

Hope this helps !
