Answer:
x = 90
Step-by-step explanation:
First, you'll want to take the three equations you see and set them up in an addition equation to add up to 360 like so...
- 4x + 2y + x + 2y - x = 360
Since two opposites add up to zero, they can be removed from the equation, therefore, removing (+ x) and (- x) from this equation:
Collect like terms (2y and + 2y):
Move the variable (+ 4y) to the right hand side of the equation and change its sign:
Divide both sides of the equation by 4.
x = 90 - y
Ignore the i y and you got your answer. x = 90. Hope this helped!
Answer:
Son = 14
Father = 42
Step-by-step explanation:
Let son age be x
Father's age is 3x and x + 28
3x = x + 28
2x = 28
x = 28/2 = 14
Father's age is x + 28 = 42
