Complete the solution of the equation. find the value of y when x equals -3. -x + 3y = 18

5

Step-by-step explanation:

-x + 3y= 18

X= 3

-(-3)+3y =18

3 + 3y= 18

Subtract 3 from both sides.

3y = 15

Divide by 3 on both sides.

Y= 5

what do you need me to answer?

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
