Answer:
x = 6
Step-by-step explanation:
110 and 19x - 4 are alternate exterior angles and are congruent, then
19x - 4 = 110 ( add 4 to both sides )
19x = 114 ( divide both sides by 19 )
x = 6
Let x = John's age now
half of what johns age was 4 years ago: (1/2)(x-4)
is equal to one third of what it will be in 5 years time: (1/3)(x+5)
(1/2)(x-4) = (1/3)(x+5)
3(x-4) = 2(x+5)
3x - 12 = 2x + 10
