Answer:

x = 16/7

Explanation:

Given

  • x/2 - 1 = 3 - x / 5

Solving

#1) Find the LCM.

  • Product of denominator values
  • 2 x 5 = 10

#2) Multiply both sides by 10.

  • 10(x/2 - 1) = 10(3 - x / 5)
  • 5x - 10 = 2(3 - x)
  • 5x - 10 = 6 - 2x

#3) Bring x terms to the left and numbers to the right.

  • 5x + 2x = 6 + 10
  • 7x = 16
  • x = 16/7

x = 16/7

Step by step explanation :


(x)/(2) - 1 = (3 - x)/(5)

Taking LCM in Left Hand Side


⇢ (x - 2)/(2) = (3 - x)/(5)

Now, By cross multiplying ,we get. ..


⇢5(x - 2) = 2(3 - x)


⇢5x - 10 = 6 - 2x


⇢5x + 2x = 6 + 10


⇢7x = 16


⇢ \boxed{ x = (16)/(7) }
