Answer:
1. g/6=x
2. (u+2)/2=x
3. m/z=x
4. g/c=a
5. u+k=x
6. g-c = x
7. k/u = a
8. g/c =x
9. 4/(12m)=a or 1/(3m)=a this is the simplified version
10. (-3-2c)/-3=x x=1+2c/3 Teachers usually prefer the first one
Step-by-step explanation:
so for this, they aren't looking for exact answers they just want you to get the variable they are looking for by itself
1. you want to get x by itself so you divide both sides by 6
g/6=x
2. same thing here you want x by itself. First, you add 2 to both sides
(u+2)=2x
x is still not by itself so divide both sides by 2
(u+2)/2=x
3. you want x by itself so there are two ways to go about this
You could add x to both sides
z+x=m and then subtract z from both sides leaving you with x=m-z or
subtract m from both sides
z-m= -x divide both sides by -1 which you will then get -z+m=x and with some rearranging that is still equal to m-z=x
4. you want a by itself so divide both sides by c
g/c=a
5. add k to both sides to get x by itself
u+k=x
6. subtract c from both sides to get x by itself
g-c=x
7. you want a by itself so to get rid of the fraction multiply both sides by a
ua=k and then divide both sides by u to get a by itself a=k/u
8. want x by itself so divide both sides by c this is very similar to problem 4
g/c=x
9. you want a by itself so you divide both sides by 12
am=4/12 this is equivalent to am=1/3 then divide by m cause a is still not alone a=1/3 divide by m. you have to do the reciprocal of m because you are dividing by a fraction so it will be like 1/3 * 1/m =a which is 1/(3m)=a
10. subtract 2c from both sides since we are trying to get x by itself
-3x= -3 - 2c X is still not by itself so divide by -3 on both sides
x=(-3-2c)/-3 = 1+2c/3 these are equivalent usually teachers will prefer the first one
