I need help on this mathe equation because I dont understand it
waht is the value of when y= 3x -1
This question is asking you find the x and y value. You have to solve it in two steps because you will have two answers. You start by plugging zero's into the x and y, one at a time. If you put a zero into the y's space, then you will add one to both sides. Your new equation will read +1=3x. then you will divide both sides by 3 and your answer will be 1/3=x. You see?
Now take the original equation again (y=3x-1) and put a zero where the x is. so now you will have 3 times 0, which is equal to ... 0. Now all that you will have left is y=-1.
So your two answers are 1/3=x and -1=y
Try this problem out y=12x+3, you should get -1/4=x and y=3.
