A box contains toffee, coffee, orange, mint and hazelnut flavour chocolates.
The ratio of toffee: coffee: orange: mint chocolates is 5:4:2:3
The probability of picking a hazelnut chocolate is
How many hazelnut chocolates are in the box?

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
