Question

solve the equation y=2x for x
solve the equation 3y +z = 13 for z
how do you do these problems? please explain along with the answer

Answer 1

y = 2x
what do you have to do to 2x to get 1x?

Answer 2

you 2x by 2

Answer 3

divide*

Answer 4

correct
what you do to one side of an equation you do to the other to keep the balance
so since you divide by 2 on the right you do the same on the left

Answer 5

oh, so it would by y over 2?

thanks for the help!

Answer 6

agree x = y/2?

Answer 7

for the 2nd one same principle
isolate the variable to one side of the equation then do what is necessary to make the coefficient = 1 and remember to keep the balance.

Answer 8

3y +z = 13
to isolate z to one side what do you need to do?

Answer 9

i subtract the 3y
would that mean that x=13-3y?

Answer 10

z

Answer 11

yes

Answer 12

alright thanks!

Answer 13
