Answer:
TRUMP WON 2021
Step-by-step explanation:
Answer:
present Age of " A " will be (x) = 45 years
present Age of " B " will be (y) = 24 years
Step-by-step explanation:
Age of " A " = x years
Age of " B " = y years
(Three years ago A's age was double of B's age.)
==> (x-3) = 2 * (y-3)
==> x - 2y = -6 + 3
==> x - 2y = -3 -------------(1)
(Seven years hence, the sum of their ages will be 83 years )
==> (x+7)+(y+7) = 83
==> x + y = 83 - 14
==> x + y = 69 ------------(2)
Subtract equ.(1) & equ(2)
==> -2y - y = -3 - 69
==> -3y = -72
==> y = -72/(-3)
==> y = 24
Keep value of y in equ(2)
==> x + 24 = 69
==> x = 69 - 24
==> x = 45
Subtract 8 from 66, and then divide by two to find Thomas' age. Add 8 to that, and you will have Julian's.

Solve the following system:
{y = 6 x - 24
{x = 9 x
In the second equation, look to solve for x:
{y = 6 x - 24
{x = 9 x
Subtract 9 x from both sides:
{y = 6 x - 24
{-8 x = 0
Divide both sides by -8:
{y = 6 x - 24
{x = 0
Substitute x = 0 into the first equation:
{y = -24
{x = 0
Collect results in alphabetical order:
Answer: {x = 0
{y = -24
