Cross-multiply

5x  = 35

Divide both-side of the equation by 5

 =  

(On the right-hand side of the equation, 5 at the numerator will cancel-out 5 at the denominator leaving us with just x, while on the left-hand side of the equation 35 will be divided by 5)

x = $7

Therefore, one pound costs $7
