400 - 2x = 244
Therefore, 2x = 400 - 244 = 156
Therefore, x = 156/2 = 78
Therefore, you would be 78 years old.

If: 500-4x = 128 then the value of x = 93 years of age
500-4x=232 -4x=-268 x=67
500 - 335 = 165 165 ÷ 3 = 55 So you are 55 years old.
The boy is 18 and the girl is 9
188
Let the age be x:- If: 400-3x = 163 Then: x = 79
Let the age be x and so if 400 -3x = 163 then the value of x works out as 79
Let the age be x:- 400-3x =178 -3x = 178-400 -3x = -222 x = 74
Let the age be x and so if 400 -3x = 163 then x works out as 79 years of age
The algebraic formula for this problem is: 160 = 400 - 4y Where y is your age. Rearranging gets you: 400 - 160 = 4y 240 = 4y 60 = y So you are 60.

If: 500-4x = 128 then the value of x = 93 years of age
500-4x=232 -4x=-268 x=67
(500 - 148)/4 ie 352/4 = 88
300 - 2n = 126 2n = 174 n = 87
