3,6,8,5, these are your answers
2(x-5)=20
Divide both sides by 2 (division of property equality)
x - 5 = 10
Add 5 to both sides (addition of property equality)
x = 15
Answer
x = 15 is the solution
Let x= months
So 50x is the total amount he pays after x months. You went to add 100 to this because there's a fixed cost of 100 for the phone
So you have the expression 100+50x which is the amount he pays after x months
Since he has a limit of 300,
100+50x < 300
Answer: 4x - 6 = 563
Suma 6 a ambos lados para aislar la variante 4x.
4x - 6 = 563
+6. +6
4x = 569
Divide ambos lados por 4
4x/4 = 569/4
X = 142.5
