The sum of two numbers is 23. the difference of twice the second number and the first is 1. write and solve a system of equations to find the number. (use the elimination method)

8 and 15

Step-by-step explanation:

Lets say x+y=23.

2y-x=1

System of equation:

x+y=23

2y-x=1

So 3y=24

So y=8

x=15

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
