Find the value of y that makes each equation true for all values of x x+5+11x=12x+y
Readme [11.4K]
Ok, let's simplify the left side first by adding the x's together
We get:
12x+5=12x+y
So if we subtract 12x from each side, it cancels it out on both sides, leaving us with 5=y or y=5

If we plug that back into the original we simplified of 12x+5=12x+y, we would have: 12x+5=12x+5, which is true.  :D

Which expression represents the following statement? Multiply 6 by 3, and then subtract the quotient of 18 and 9.
FromTheMoon [43]

Answer:

C) (6 x 3) - 18 ÷ 9

Step-by-step explanation:

I'll solve this question by writing down every step and doing it one by one.

1. Multiply 6 by 3

--> This will be represented as 6 x 3.

2. Subtract the quotient of 18 and 9

--> The quotient is a number resulting in a division of another number. In this case, 18 is bigger than 9, so the quotient will be: 18 ÷ 9.

--> Since we are subtracting this from the equation we got earlier, it can be expressed as (6 x 3) - (18 ÷ 9)

This equation is the same as C) (6 x 3) - 18 ÷ 9, so C is our final answer.
