2x=y
×+y=36
x=Ed's age
y=His brothers age
Then you plug in Y into the secound equation.
×+2×=36.
You then add the two x together.
3x=36
The to get x by itself you take 36 and dive by 3 to get 12.
x=12
Then plug 12 into the equation
12+y=36
Then get y by itself.
y=24.
So, Ed's age is 12 and Ed's brother's age is 24.
Is there something wrong with the question?
False. x/3 represents x as the part of a whole, or x divided by 3. 1/3 x represents 1/3 of x or 1/3 times x. Hope that helps!
