Answer:
1st One goes to the third one
2nd one goes to the 1st one
3rd one goes to the 4th one
and the 4th one goes to the 2nd one
Step-by-step explanation:
let both unknowns be x and y
x = 5y. ......(1)
x + y = 90. ......(2)
sub eqn (1) into eqn (2)
5y + y = 90
6y = 90
y = 90/6
= 15
sub y = 15 to eqn (1)
x = 5y
x = 5 × 15
× = 75
x = 12 , y = 18 (12, 18) is the solution, intersection of the two lines.
