i neeed helpppppp

What's the question?

OpenStudy (anonymous):

^

OpenStudy (anonymous):

i need to change this linear equation to standard form 10y-3x+6=11

OpenStudy (agent0smith):

Standard form is Ax+By=C A, B, C are all integers, GCF of 1, and A is positive. So, get all the x's and y's on one side, leave all the numbers on the other.

OpenStudy (anonymous):

howww

OpenStudy (agent0smith):

You already have the x's and y's on one side, so get all the numbers on the other, by subtracting 6 on both sides

OpenStudy (anonymous):

ok i have 10y-3+6=5

OpenStudy (anonymous):

3x*

OpenStudy (agent0smith):

That's not correct, only the right side is. Subtract 6 on BOTH sides of: 10y-3x+6=11

OpenStudy (agent0smith):

That's good. THen do you see the mistake you made in this... 10y-3+6=5

OpenStudy (anonymous):

okokokokok 10y-3x=5 not what

OpenStudy (anonymous):

now*

OpenStudy (agent0smith):

Good. Now, change the order so the x comes first 10y - 3x = 5 becomes -3x + 10y = 5 Now one more step... the number in front of x needs to be positive.

OpenStudy (shamil98):

10y-3x+6=11 10y - 3x = 5 -3x +10y = 5 3x + 10y = -5

OpenStudy (anonymous):

soo i just move it over?????

OpenStudy (agent0smith):

to make the x positive? no. Multiply both sides by -1.

OpenStudy (shamil98):

oh my bad, 3x - 10y = -5
