Solve for w.<br> 2w=12-4w<br> Simplify your answer as much as possible.
aev [14]
So we have an equation:
2w=12-4w
Firstly, let's simplify, and divide all terms by 2:
w=6-2w
Now, we add 2w over to the other side:
3w=6
And finally, we divide both sides by 3:
w=2
Hope this helps!

The type of equation given below is in point-slope form <br> y=1/2x-5 true or false
kykrilka [37]

Answer:

false

Step-by-step explanation:

point slope form : y - y1 = m( x - x1 )

the equation y = 1/2x - 5 does not follow this therefore the answer is false

the equation y = -1/2x - 5 is instead put in slope intercept form , y = mx + b
