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.

Where on a number line are the numbers x for which <br><br>|x|&gt;1
Andrews [41]

Answer:

Step-by-step explanation:

Given the inequality

|x|> 1

The modulus of x shows that x can be both positive and negative value.

If x is positive:

x>1

1<x

If x is negative:

-x>1

Multiplying both sides of the inequality by minus will change the inequality sign

x < -1

Combining both inequalities:

1<x<-1
