6x+3y=15 for y. What does y equal if x=2?if x=5?

if x = 2 , y = 1

if x = 5 , y = -5

Step-by-step explanation:

6(2) + 3y = 15

12 + 3y = 15

12 + 3(1) = 15

y = 1

6(5)+3(y) = 15

30 + 3(-5) = 15

30 - 15 = 15

y = (-5)

1 and -5

Step-by-step explanation:

let's start with moving y to one side for convenience sake.

6x+3y=15

subtract 6x on both sides

3y=15-6x

divide by 3 on both sides

y=5-2x

all you have to do is replace x with whatever number you want it to equal. starting with 2:

y=5-2(2)=5-4=1

now let's replace x with 5

y=5-2(5)=5-10=-5

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false

step-by-step explanation:

i dont know what you want me to answer for this but im guessing 2: 11?
