Solve the expression and find the value of x.

vovangra [49]

$\large\underline{\sf{Solution-}}$

$\sf \dfrac{x + 1}{10} - \dfrac{3(x - 1)}{5} = 2$

$\sf\longmapsto \dfrac{x + 1}{10} - \dfrac{3x - 3}{5} = 2$

$\sf\longmapsto \dfrac{(x + 1) - 2(3x - 3)}{10} = 2$

$\sf\longmapsto \dfrac{x + 1 - (6x - 6)}{10} = 2$

$\sf\longmapsto \dfrac{x + 1 - 6x + 6}{10} = 2$

$\sf\longmapsto \dfrac{ - 5x + 7}{10} = 2$

$\sf\longmapsto - 5x + 7 = 20$

$\sf\longmapsto - 5x = 20 - 7$

$\sf\longmapsto - 5x = 13$

$\sf\therefore x = - \dfrac{13}{5}$

Hence, the value of x will be -13/5 respectively.

Let a = 2i + 3, b= i – 1, and c= -3i + 2. Which expression is equivalent to a -b- c?A. –2i +4B. 4i + 2C. 4i + 4D. -2i + 2

34kurt

Given:

$\begin{gathered} a=2i+3 \\ b=i-1 \\ c=-3i+2 \end{gathered}$

You know that:

$a-b-c=(2i+3)-(i-1)-(-3i+2)$

In order to solve the operation, you can follow these steps:

1. Distribute the negative signs. Remember the Sign Rules for Multiplication:

$\begin{gathered} +\cdot+=+ \\ -\cdot-=+ \\ +\cdot-=- \\ -\cdot+=- \end{gathered}$

Then:

$=2i+3-i+1+3i-2$

2. Combine the like terms (add the Real Parts and add the Imaginary Parts):

$=4i+2$

Hence, the answer is: Option B.
