Solve the equation 4n -3=2n + 5 for n

OpenStudy (camerondoherty):

Ok first you add 3 to both sides of the equation

OpenStudy (camerondoherty):

4n = 2n + 8

OpenStudy (anonymous):

so it would be 4n

OpenStudy (camerondoherty):

no wait

OpenStudy (camerondoherty):

then you divide 4n by 2

OpenStudy (camerondoherty):

hold on i think i messed up -_-

OpenStudy (precal):

4n-3=2n+5 yes add 3 to both sides

OpenStudy (precal):

4n=2n+8 -2n -2n to both sides

OpenStudy (precal):

2n=8 one last number to move

OpenStudy (precal):

how do you undo a multiplication?

OpenStudy (camerondoherty):

sorry about that -,-

OpenStudy (precal):

2 times n, what number do you move and how would you move it?

OpenStudy (precal):

@camerondoherty np

OpenStudy (anonymous):

so the answer is 2n

OpenStudy (precal):

2n=8 2 times what number gives you 8?

OpenStudy (anonymous):

4

OpenStudy (precal):

2n=8 divide 2 to both sides n=4

OpenStudy (anonymous):

thank you so much

OpenStudy (precal):

np learn to solve equations as you learn more advance math, you will need these skills
