 Solution Find x prop y and x=4 when y=2. Find y when x=18Solution:Your problem -> x prop y and x=4 when y=2. Find y when x=18x prop y=> x=K*yNow, x=4,y=2=> 4 = K * 2=> K = (4)/(2)=> K = 2Hence, x=2*yy=?,x=18=> 18 = 2 * y=> (18)/(2) = y=> y = 9 Solution provided by AtoZmath.com Any wrong solution, solution improvement, feedback then Submit Here Want to know about AtoZmath.com and me
