Minus 6 both sides
y-6=4x+rx
undistribute x
y-6=x(4+r)
dividie both sides by (4+r)
y-6=4x+rx
undistribute x
y-6=x(4+r)
dividie both sides by (4+r)
We sketch the two similar shapes and they are as shown in the attachment. We want to write corresponding side's length in ratio
Writing the two ratio as fraction gives
Cross multipliying gives
