Answer:
3x-4=107* why vertical angles
Step-by-step explanation:
3x-4=107
add 4 on both sides
3x=111*
x=37
Y - x = 154
let z = xy = x(154 + x) = x^2 + 154x
we need to find the minimum value of z
z' = 2x + 154 which = zero for minm or maxm value
x = -77 and y = 154 -77 = 77
so the 2 numbers are -77 and 77
