9+4(x+1)=25

OpenStudy (campbell_st):

if you need to solve for x 1. subtract 9 from both sides of the equation 2. divide both sides of the equation by 4 then you should be close to finding x... its a very simple step

OpenStudy (anonymous):

please explain

OpenStudy (campbell_st):

by subtracting 9 from both sides will leave 4( x + 1) = 16 now divide both sides of the equation by 4...

OpenStudy (anonymous):

still not understanding

OpenStudy (campbell_st):

ok so its \[\frac{4(x +1)}{4} = \frac{16}{4} \] can you simplify this..?

OpenStudy (anonymous):

its not showing ur picture

OpenStudy (campbell_st):

its an equation.... created by the equation editor...

OpenStudy (anonymous):

oh I c it

OpenStudy (anonymous):

so the answer is 2 ??

OpenStudy (campbell_st):

no ... sorry.... what did you get when you divided by 4..?

OpenStudy (anonymous):

2

OpenStudy (campbell_st):

nope.... maybe this will help... \[\frac{4 \times (x + 1)}{4} = \frac{4 \times 4}{4} \]

OpenStudy (anonymous):

x=4??

OpenStudy (campbell_st):

nope... have a look at the equation.... what do you get if you divide each side of the equation by 4...?

OpenStudy (anonymous):

idk

OpenStudy (campbell_st):

ok... here is another method 4 times something = 16 whats the something...?

OpenStudy (ghdoru11):

9+4x+4=25 4x+13=25 4x=25-13 4x=12 x=12/4 x=3
