Sara is baking several batches of brownies to sell in her bakery. She used 8 cups of oil and 10 cups of flour. How many cups of oil was used per cup of flour?

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

thats not a system of equations, that is a solution
