The equation 4(x - 2) = 100 is a true equation for a particular value of x. Explain why 2(x - 2) = 50 is also true for the same value of x.

Question

The equation 4(x - 2) = 100 is a true equation for a particular value of x. Explain

why 2(x - 2) = 50 is also true for the same value of x.

Answer 1

have line equation

y₁=4(x-2)

let y₂=y₁/2

for any chosen y₁,,,

y₂=(4(x-2))/2=2(x-2)

and y₂=y₁/2

y₁=100

y₂=2(x-2)=50
