Solve for t:-
y + y = t
y = 8
Substitute for y:-
8 + 8 = t
8 + 8 = 16
t = 16
The answer is: " x = 75 units ".

Set up the follow ratios, or proportions, as fractions:
x/ 63 = 50/42; Solve for "x" ;
________________________________________________________
→ Reduce the "50/42" ; " 50/42" = (50÷2) / (42÷2) = 25/21 .
Rewrite: " x / 63 = 25 / 21 " .
Cross multiply: Given: "a/b = c/d " ; "ad = bc" ;
Thus, "21x = (63) * (25) ;
Divide each side of the equation by "21" ; to isolate "x" on one side of the equation; and to solve for x" ;
" 21x / 21 = [ 63 * 25 ] / 21 " ;
Note: "63/21 = 3 " ;
So: x = 3 * 25 ;
