Answer: B (2,1)

You know what y is (x-1) so you substitute that for y in the other equation.

3x+ ((4)(x-1))=10

3x+4x-4=10

7x=14

x=2

Then put x=2 into y=x-1

y=2-1

y=1

Fifteen more than a number is written as...?

frozen [14]

Answer:

x + 15

Step-by-step explanation:

Since I don't know what this number is, I'm going to use the variable x to substitute for the value of the unknown number.

So it would just be x + 15 because addition is the operation of adding and the key words are usually more. Since one of the numbers is unknown, we can't get an answer like "100" because x is undefined.

Say x=100, then the number would be written as 115 in it's simplest form but you could also write it as 100+15. So I'm just using substitution.
