Question

Solve for x in 12x + 4y = 16

Answer 1

`x = ( 16 - 4y)/(12)`

Explanation:

12x + 4y = 16

12x + 4y - 4y = 16 - 4y

12x = 16 - 4y

`(12x)/(12) = ( 16 - 4y)/(12)`

`x = ( 16 - 4y)/(12)`

Answer 2

y = -3x+ 4

one equation two unknows can not solve uniquely

4y = -12x + 16

y = -3x+ 4

is the solution set
