Required Answers:-

We need to find the value of x in each of the questions listed above in the attachment. These are examples of linear equation in one variable.

  •   \boxed{\rm{\frac{2x - 7}{3}  = 1}}

Cross multiply,

⇒2x - 7 = 1 × 3

⇒2x - 7 = 3

Add 7 in both sides,

⇒2x = 10

Divide 2 in both sides,

x = 5

  •  \boxed{\rm{2x + 4 = 5x - 5}}

Add 5 in both sides,

⇒2x + 4 + 5 = 5x

⇒2x + 9 = 5x

Now flip the equation,

⇒5x = 2x + 9

Subtract 2x from both sides,

⇒3x = 9

x = 3

  •  \boxed{\rm{ \frac{x}{3}  + 5 =  \frac{x}{2}  + 4}}

Take the LCM in both sides,

⇒(x + 15)/3 = (x + 8)/2

Cross multiply,

⇒2(x + 15) = 3(x + 8)

Opening the parentheses,

2x + 30 = 3x + 24

Subtract 24 from both sides,

⇒2x + 6 = 3x

Subtract 3x from both sides,

⇒-x + 6 = 0

x = 6
