12x-2x = -2 (4-x)
12x-2x = 8 + -2x
Get rid of -2x from both sides (this is only because they both have it if only one side had it we would not just get rid of it)
12x =8
Divide both sides by 12
X = 8/12 or 2/3

A man can buy 20 mangoes or 30 oranges. If he wants a each amount of each, how many of each would he get? Write an EQUATION to s

DochEvi [55]

Answer:

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 $\frac{1}{20}$ z and the oranges price is $\frac{1}{30}$ z. The equation for money and number of mangoes and oranges will be:

money = mango price * mangoes bought + orange price * orange bought

z= $\frac{1}{20}$ z * x + $\frac{1}{30}$ z *y

1= $\frac{1}{20}$ x + $\frac{1}{30}$ y

- $\frac{1}{30}$ y= $\frac{1}{20}$ 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= $\frac{30}{2.5}$ = 12
