-3x+5=-7x-4
First add 7x to both sides so
4x+5=-4
Then subtract 5 from each side so
4x=-9
Then divede each side by 4 so the answer is
x=-9/4

-3x +5 = -7x -4
exchange terms putting all the x's at the left side and the constants at the right.
-3x + 7x = -4 -5
add
4x = -9
divide both sides by 4
x = -9/4

First you want to get the variables on one side and the integers on the other....
thus you Add 7x to both sides and subtract 5 from both sides
this gives you 4x = -9
divide both sides by 4 and you get
x = -9/4 or x = -2 1/4

bring x terms to the left and constant to right
-3x + 7x = -5-4
or 4x = - 9
devide by 4
x = -9/4

-3x +5 = -7x -4
-3x +5 +7x = -4
4x +5 = -4
4x +5 - 5 = -4 – 5
4x = -9
4x/4 = -9/4
x = -9/4

7x - 3x = - 4 - 5
4x = - 9
x = - 9/4

-3x + 5 = -7x - 4
+7x - 5 = +7x -5
---------------------
4x = -9
/4 = /4
