64x+24= 8(8x+3)
30x+70= 10(3x+7)
6.90 i think i may be incorrect
(25, 160) and (50, 320)
(y2-y1)/(x2-x1)
(320-160)/(50-25)
160/25 = slope
Y = 6.4x + b
Plug in points and solve for b
Let us consider that Christopher is 'x' years old
Age of Christopher = x
George is 8 years more than Christopher
Age of George = (x + 8)
Ford is 2 years younger than Christopher
Age of Ford = (x - 2)
Now the sum of their ages is 60
∴ x + (x + 8) + (x - 2) = 60
3x + 6 = 60
3x = 60 - 6
3x = 54
x = 54 ÷ 3
x = 18
Age of Christopher = x = 18 years
Age of George = (x + 8) = 18 + 8 = 26 years
Age of Ford = (x - 2) = 18 - 2 = 16 years
The sum of all their ages = 18 + 26 + 16 = 60 years
