Solve the equation for y: 4x + 3y = -12
you can only get y in terms of x. In which case keep y on left hand side and shift all the other terms to the right and side, That should fetch you the answer!
subtract 4x from both sides then divide it al by 3
I still can't get the answer.
-12-4x the whole divided by three
bt then ull have to know whats x
\[y=-12-4x \div3\]
do u know wats x
You cannot solve for both y and x, with only one equation, In general if you have n variables you need n equations, so in this case we have 2 variables so we would need 2 equations to solve them. They come under the category of simultaneous linear equations.
x is a variable if you plot a graph a straight line will form
I got -4 for the overall problem is that correct?
That is wrong, you cannot get a number as an answer @TheWiz
So what's the answer? & how did yu get the answer?
your answer is (-12-4x)/3
First take 4x to the other side, so it becomes -12-4x, then divide the whole by 3 which will give you the resulting answer.
