Explanation:
"using the method of "color(blue)"cross-products"
•color(white)(x)a/b=c/drArrbc=ad
rArr5t=2(t-6)
rArr5t=2t-12
"subtract "2t" from both sides"
5t-2t=cancel(2t)cancel(-2t)-12
rArr3t=-12
"divide both sides by 3"
(cancel(3) t)/cancel(3)=(-12)/3
rArrt=-4
color(blue)"As a check" Substitute this value into the equation and if both sides are equal then it is the solution.
"left "=2/(-4)=-1/2
"right "=5/(-4-6)=5/(-10)=-1/2
rArrt=-4" is the solution"
