Question

Given that 12 years ago

Answer 1

I think the value of x=16

Answer 2

in the rhombus above, W = Y, but W = x+3, and Y = 2x-13, thus
x+3 = 2x-13

solve for "x"

Answer 3

10?

Answer 4

10? dunno, just solve for "x" :) what does it give you?

Answer 5

i got 10

Answer 6

let's see
x + 3 = 2x -13
# substract "x" from each side
x + 3 -x = 2x -13 -x => 3 = x -13
# add 13 to each side

3 + 13= x -13 + 13 => ?
