Question

Value of x in the given equation

18=5+13(x-3)

Answer 1

Answer:

18=18{x-3}

18/18=X-3

1=x-3

x=3+1

X=4

Answer 2

Gívєn :

• 18=5+13(x-3)

Tσ fínd :

• Value of x

Sσlutíσn :

• 18=5+13(x-3)
• 18=18 (x-3)

$\sf\frac{18}{18}$ = x-3

$\sf\frac{\cancel{18}}{\cancel{18}}$ = x-3

• 1=x-3
• x=3+1
• x=4

:$\implies{\underline{\boxed{\green{\sf{x \: = \: 4}}}}}$

                           Laws of exponents :–

• am × an= a m+n
• 2³ × 24 = 27
• 22/3 × 21/5 = 2 2/3 + 1/5 = 2(10+3)/15 . We get, = 212/15
• (-6) 3 x (-6) 2 = (-6) 3+2 = (-6) 5
• am ÷ an = a
• 25 ÷ 23 = 2²
• p6 ÷ p2 = p 6 – 2 = p 4
• (am)n = am×n
• ( 53 )2 = 53×2 = 510 (approx)
• ab^n = anbn
• 25^12 = 212512
