Answer:
x = 8
Step-by-step explanation:
200x - 100x + 57,600 = 60,000 - 200x
100x + 57,600 = 60,000 - 200x
300x = 2,400
x = 8

Answer:
12
Step-by-step explanation:
In this question, there are two variables: the number of mangoes(y) bought and the number of oranges bought(x).
Let's say the man have z money, mangoes price is z and the oranges price is z. The equation for money and number of mangoes and oranges will be:
money = mango price * mangoes bought + orange price * orange bought
z= z * x + z *y
1= x +y
-y= x -1
y= -1.5x + 30
y= 30 - 1.5x
If he want equal number of mango and orange, that mean y=x. The calculation will be:
y= 30 - 1.5x
x= 30 - 1.5x
x+ 1.5x = 30
2.5x= 30
x= = 12
Answer:
x = 10
Step-by-step explanation:
soln
9x - 40 = 3x + 20
9x - 3x = 20 + 40
6x = 60
x = 10
