Question

If x/9 + 2= 240+ 9x then find the value of x.

Answer 1

Step-by-step explanation:

Given 9x+2 = 240 + 9x

⇒ 9x x 92= 240 + 9x

let 9x = a

⇒ 81a = 240 + a

⇒ 80a = 240

⇒ a = 3

but 9x = a

⇒ 9x = 3

⇒ 32x = 3

bases are equal powers should be equated.

⇒ 2x = 1

⇒ x = 1/2.

Answer 2

Answer:

x = -26.775

Step-by-step explanation:

x/9 + 2 = 240 + 9x

=> x/9 - 9x = 240 - 2

=> x - 81x = 9(238)

=> -80x = 2142

=> x = -2142÷80

=> x = -26.775
