could someone please crique this algebra x must be the subject
6y = 9 - 3x
3x = 6y + 9
x = 2y + 3
is this correct please
Add 3x to each side.Giving 6y+3x=9.
Subtract 6y from each side.Giving 3x=9-6y.
Divide each side by 3.Giving x=(9-6y)/3.
Divide numerator by 3.
Giving x=3-2y.
To critique this algebra, let's simplify and rearrange the equations to have x as the subject:
Equation 1: 6y = 9 - 3x
To isolate x, we need to move all terms with x to one side and all other terms to the other side:
6y + 3x = 9
Next, we can rearrange the equation to get x alone:
3x = 9 - 6y
Dividing each term by 3 gives us:
x = (9 - 6y) / 3
This equation can be further simplified:
x = 3 - 2y
So the correct equation with x as the subject is x = 3 - 2y.
In conclusion, the rearrangement provided x = 3 - 2y is correct.
