Solve for "x" in the equation....
-3x + 4y = 11
First: subtract 4y from both sides (when you move a term to the opposite side, always use the opposite sign).
- 3x + 4y - 4y = - 4y + 11
- 3x = - 4y + 11
SEc: solve for "x" by isolating the variable on one side - divide each term by -3.
- 3x/-3 = - 4y/-3 + 11/-3
x = 4y/3 - 11/3 Or, (4y - 11)/3

-3x + 4y = 11
Isolate the x on one side
4y - 11 = 3x
Divide through by x co-efficient
(4y - 11)/3 = x
x = (4y - 11)/3

First, move 4y to the other side of the equation to isolate x.
-3x + 4y = 11
-4y -4y
-3x = -4y + 11
Now, to get x by itself, divide by -3.
x = -4y + 11 / -3
Done. =)

3x=4y-11
x=4/3y-11/3

-3x + 4y= 11
.......-4y...-4y
-3x.......= -4y +11
___........ ______
-3...............-3
x= -4y + 11
......______
.........-3
that is how it should be written on the paper... but move the lines (underscores)(_____) under the numbers & variables above them..... ignore the dots(....) i had to use them for spacing...
