Question

Samosa contain half as many as they are in one french fries. Total calories in french fries and samosa is 450. Set up an linear equation.

Is the linear equation x +y =450 or is it something else?

Answer 1

the linear equation here is not x+y=450 but it is x +2x = 450 as the french fries have double the calories. solution:

x+2x=450
x+2x=3x=450
x(samosa)=450/3=150
2x(french fries)=150*2=300

Answer 2

x+1\2x=450
so 3x/2=450
so 450x2=3x
so 900=3x
so x=30
