Answer:
the substitution method is one way to solve linear equation. the substitution method is when substitute the one y value with the other:
example :
x+y=10
y=10-x ( value of y)
2x+y=12 ( substitute the value of y in the equation )
2x+(10-x)=12
2x+10-x=12 ( now solve for x)
x=12-10
x=2 ( substitute the value of x in the equation x+y=10)
x+y=10
2+y=10
y=10-2
y=8

If they are proprtional which is what the ~ means then
BA/AC=ED/CD
42/x=6/(32-x)
solve
divide both sides by 6
7/x=1/(32-x)
multiply both sides by (x)(32-x)
7(32-x)=x
distribute
224-7x=x
add 7x to both sides
224=8x
divide both sides by 8
28=x
x=28
