Answer:
b)Add the equations to eliminate x.
Step-by-step explanation:
y= x+20
y= - x+2
Result of the addition: (-x cancels x)
2y = 22
y =11
11=x +20 -9 = x
11=9+2
11 = -9 +20

Hope this helped.
The easiest way to solve a problem like this is to cross multiply and solve
The problem gives us a ratio
2 pounds of granola = 3 pounds of raisins
which makes a ratio of
The other ratio is
? pounds of granola = 24 pounds of raisins
which makes a ratio of
To solve, set them equal to each other ...
Now we must cross multiply...
To cross multiply, we multiply
2 and 24 and we multiply
3 and x Now we have an equation to solve!
3x = 48 To solve and get your final answer, divide...
x = x = 16
You'll need 16 pounds of granola
