Solve the followimg equation 5(x-3 ) = 3 (x+2)​

Answer»

Required Solution:

⇒ 5 ( x - 3 ) = 3 ( x + 2 )

⇒ 5(x) + 5 (-3) = 3(x) + 3(2)

  • Now, performing multiplication.

⇒ 5x - 15 = 3x + 6

  • Transposing like terms.

⇒ 5x - 3x = 6 + 15

  • Performing subtraction in LHS.

⇒ 2x = 21

  • Transposing 2 from LHS to RHS.

⇒ x = \dfrac{21}{2}

Value of x is 21/2.

Verification:

Substitute the value of x in LHS and RHS.

⇒ 5 ( x - 3 ) = 3 ( x + 2 )

⇒ 5 ( \dfrac{21}{2} - 3 ) = 3 ( \dfrac{21}{2} + 2 )

⇒ 5 ( \dfrac{21-6}{2} ) = 3 ( \dfrac{21+4}{2} )

⇒ 5 ( \dfrac{15}{2} ) = 3 ( \dfrac{25}{2} )

⇒ 5 × \dfrac{15}{2} = 3 × \dfrac{25}{2}

⇒ \dfrac{75}{2}= \dfrac{75}{2}

LHS = RHS

Hence, VERIFIED!!
