The equation 4(x-2) = 100 is a true equation for a particular value of x . Explain why is also true for the same value of x . To solve 7.5d=2.5d the equation , Lin divides each side by 2.5d , and Elena subtracts 2.5d from each side x.

a. Will both moves lead to the solution? Explain your reasoning.

b. What is the solution?

Find the constant of variation for the relation and use it to write an equation for the statement. then solve the equation.
