PLEASE LOOK IN THE BOTTOM OF THIS MESSAGE......
solve for x:
3x - 2y = 6
i need help in solving this:
the possible answers has to be one of these:
A)2y +6 divided by 3
b)3x -6 divided by 2
C) 2 + 2y
D) 2/3y + 6
but how i keep trying and i don't get non of these.

Add 2y to both sides of the equation. That will give you
3x = 2y + 6
Then divide both sides of the new equation by 3 and you will see what x is.
It will be one of the choices
I STILL GET THE FOLLOWING:
X =2/3Y + 2
BUT ONE OF MY CLASSMATES SAYS THAT THATS WRONG BECAUSE IT HAS TO BE:
X = 2 +2Y
x = (2/3) y + 2 is the same thing as
x = (2y + 6)/3
Your answer is correct, but the multiple choice to make in this case is (A), which is another way of writing the same thing
Your classmate is wrong
how would you check this:
i mean you know how in alot of equations we can check them how would i do it with something like this.
sorry i didn't realize that my sister posted up something but the previous message is mine. she didn't erase her name.
To check whether your solution is correct, you can substitute the value of x into the original equation and see if it satisfies the equation.
Let's check the solution x = (2/3)y + 2:
Plug in this value of x into the original equation:
3x - 2y = 6
3((2/3)y + 2) - 2y = 6
Simplify the equation:
2y + 6 - 2y = 6
6 = 6
The equation simplified to 6 = 6, which is true. Therefore, x = (2/3)y + 2 is a valid solution to the equation 3x - 2y = 6.
