Answer:
x = 
or 0.706
or 1.735
Step-by-step explanation:
5x + 2y=7 ----->(eq 1)
- 2x + 6y=9 ----->(eq 2)
Multiply (eq 1) with 3
3×(5x + 2y) = 3×7
15x + 6y = 21 ----->(eq 3)
substract (eq 3) from (eq 2)
- 2x + 6y - (15x + 6y) = 9-21
- 2x + 6y - 15x - 6y = 9-21
- 2x - 15x + 6y - 6y = 9-21
-17x = -12
x = -12 ÷ -17
x =
put x = in (eq 1)
I will need 9.625 cups of flour
<h3>Proportions?</h3>
The ratio of two or more integers is referred to as proportion.
From the information given, we have;
- 1 kg of dough = 2.75 flour
To prepare 3 1/2 kg de masa, we will have:
Divide both expression
1/3.5 = 2.75/x
x = 2.75 * 3.5
x = 9.625
Hence I will need 9.625 cups of flour
