a=6, b=2

Step-by-step explanation:

Use simplification into substitution
$\frac{a}{3} =1+\frac{2}{b}$

$a=3(1+\frac{2}{b})$

$a=3+\frac{6}{b}$

We can now plug this value of <em>a</em> into the second equation.

$\frac{3+\frac{6}{b} }{4} +\frac{3}{b} =3$

Get rid of fractions in the numerators and/or denominators

$\frac{3b+6}{4b} +\frac{3}{b} =3$

Then we can match the denominators

$\frac{3b+6}{4b} +\frac{12}{4b} =3$

Combine

$\frac{3b+18}{4b} =3$

Divide both sides by three

$\frac{b+6}{4b} =1$

Get rid of fractions

$b+6=4b$

Single out <em>b</em>

$6=3b$

$b=2$

Now we can plug it into the equation

$\frac{a}{3} -\frac{2}{2} =1$

$\frac{a}{3} =2$

$a=6$

Now we can check it;

$\frac{6}{3} -\frac{2}{2} =1$

↑CORRECT

$\frac{6}{4} +\frac{3}{2} =3$

↑CORRECT

Sharonda uses a blend of dark chocolate and milk chocolate to make the ice cream topping at her restaurant. She needs to buy 120

White raven [17]

Step-by-step explanation:

ATQ,

Let d be the number of kilograms of dark chocolate she buys and m be the number of kilograms of milk chocolate she buys.

She needs to buy 120 kg of chocolate in total for her next order, and her recipe calls for twice the amount of dark chocolate as milk chocolate.

So,

m = 2d .....(1)

m + d = 120 ...(2)

We can also solve the above equations,

Put m = 2d in equation (2)

2d + d = 120

3d=120

d = 40

Put d = 40 in equation (1)

m = 2(40)

m = 80

Hence, she will need 40 kg of dark chocolate and 80 kg of milk chocolate.
