Question

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

Answer 1

Answer:

x=15

Step-by-step explanation:

The given equation is

$-2x+4=-\frac{1}{3}x-21$

Here the variable is x and the terms with the variable are $-2x \;and\; -\frac{1}{3}x.$

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

$-2x+\frac{1}{3}x=-21 -4$

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

$-\frac{5}{3}x=-25 \\\\\Rightarrow \frac{5}{3}x=25 \\\\\Rightarrow x=\frac{25\times3}{5} \\\\\Rightarrow x=15$

In this way, the value of x is 15.
