Question

-2х+4=-1/3х-21
Как это решить пожалуйста помогите пожалуйста решить ​

Answer 1

x=15

Explanation:

The given equation is

`-2x+4=-(1)/(3)x-21`

Here the variable is x and the terms with the variable are
`-2x \;and\; -(1)/(3)x.`

Keep all the terms having variable on one side and all the constants terms on the other side as

`-2x+(1)/(3)x=-21 -4`

Now, simplify the above equation to get the value of x as

`-(5)/(3)x=-25 \\\\\Rightarrow (5)/(3)x=25 \\\\\Rightarrow x=(25*3)/(5) \\\\\Rightarrow x=15 \\\\`

In this way, the value of x is 15.
