She can make 75 cakes with 15 cups of flour
Answer:
y = 2
Step-by-step explanation:
Addition Method:
4x - 2y = 6
2x + y = 7
-2(2x + y) = -2(7)
4x - 2y = 6
-4x - 2y = -14
-4y = -8
y = 2
Substitution Method:
4x - 2y = 6
2x + y = 7
-2y = 6 - 4x
2y = 4x - 6
y = 2x - 3
2x + (2x - 3) = 7
4x - 3 = 7
4x = 10
x = 2.5
2(2.5) + y = 7
5 + y = 7
y = 2

Answer:
x = 1
Step-by-step explanation:
First simplify and get 3x + 3 = x + 5
Then subtract x from both sides and get 2x + 3 = 5
Then subtract 3 from both sides and get 2x = 2
Divide both sides by 2 and get x = 1
