$t=0$ or $t=10$

Work Step by Step

$4*abs(5-t)=20$ $4*abs(5-t)/4=20/4$ $abs(5-t)=5$ $5-t=5$ or $5-t=-5$ $5-t=5$ $5-t+t-5=5+t-5$ $0 = t$ $5-t=-5$ $5-t+t+5=-5+t+5$ $10 = t$ $4*abs(5-t)=20$ $4*abs(5-0)=20$ $4*abs(5)=20$ $4*5=20$ $20=20$ $4*abs(5-t)=20$ $4*abs(5-10)=20$ $4*abs(-5)=20$ $4*5=20$ $20=20$
