Question

$2(x + 5) - 7 = 3(x - 2)$
​

Answer 1

Answer:

2(x+5) -7=3(x-2)

2x+10-7=3x-6

2x+3=3x-6

6+3=3x-2x

9=x

Answer 2

ANSWER:

Given:

• 2(x + 5) - 7 = 3(x - 2)

To Find:

• Value of x

Solution:

⇒ 2(x + 5) - 7 = 3(x - 2)

⇒ 2x + 10 - 7 = 3x - 6

Rearranging the like terms,

⇒ 3x - 2x = 10 + 6 - 7

⇒ x = 16 - 7

⇒ x = 9

Verification:

⇒ 2(x + 5) - 7 = 3(x - 2)

Putting x = 9,

⇒ 2(9 + 5) - 7 = 3(9 - 2)

⇒ 2(14) - 7 = 3(7)

⇒ 28 - 7 = 21

⇒ 21 = 21

⇒ LHS = RHS

HENCE VERIFIED!!!
