Answer:
1. 24
2. 50
3. 9
Step-by-step explanation:
1.
X/6 - 3 = 1
X - 18 = 6
X = 6 + 18
X = 24
To check, given we find x=24
X/6 - 3 = 1
24/6 - 3 = 1
4 - 3 = 1
1 = 1
2.
Let x = 25 (Ben's money)
Let 2x = His brother's money
2x + x = 75
2(25) + 25= 75
50 + 25 = 75
75 = 75
Therefore, Ben's brother have Php 50.00
3.
3x - 8 = 19
3x = 19 + 8
3x = 27, then divide both sides by 3
x = 9
To check, given we find x=9
3x - 8 = 19
3(9) - 8 = 19
27 - 8 = 19
19 = 19
Don't forget to double check. Hope this helps :)
