Question

Solve for x: 12x +16y = 6
a. x=1/2-3/4y
b. x= 1/2-4/3y
c. x= 2-3/4y
d. x= 2+4/3y

Answer 1

12x + 16y = 6 --- subtract 16y from both sides
12x = -16y + 6 --- divide both sides by 12
x = (-16/12)y + (6/12)
x = -4/3y + 1/2......rearranged to match answer choice : x = 1/2 - 4/3y

any questions ?

Answer 2

basically, you have to get x by itself. And remember, what you do on one side of the equal sign, you have to do on the other.
