Two times x is 8 more than y. The sum of x and two times y is 14. Write two equations and graph to find the value of y.
y = 6
y = 4
y = -4
y = -6

Option B: is the value of y

Explanation:

It is given that "Two times x is 8 more than y". Writing it as expression, we have,

It is also given that "The sum of x and two times y is 14". Writing it as expression, we have,

To find the value of y, let us solve the two equations using substitution method.

From the equation , let us find the value of x.

Now, substituting in the equation , we get,

Thus, the value of y is

is there any attachment? what are the equations?

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
