carry the x's over to one side, the numbers to the other
-7+4 = 5x - 2x
-3 = 3x
x = -1

Combine like terms.
2x - 7 = 5x - 4
2x - 5x = -4 + 7
-3x = 3
Divide both sides of the linear equation by -3 to find the vaule of x.
x = 3/-3
x = -1

first you will want to get all of the variables on one side and all of the constants on the other side
2x - 7 = 5x - 4
let's move the variables to the left by subtracting 5x from both sides
2x - 7 - 5x = 5x - 4 - 5x
that gives us -3x -7 = -4
next, add the seven to both sides to get the constants all on the right
-3x -7 + 7 = -4 + 7
so, -3x = 3
the point is to find out what x is so now divide both sides by negative 3
x = -1

2x-7= 5x-4 Get variables, and constants on their own side.
-2x+4 =-2x+4 Notice the two sides are equal.
-3= 3x <----that's what you are left with after simplifying
x= -1 divide wach side by 3 to get x by itself, and viola!!
i hope this helped.

- 7 + 4 = 5x - 2x
- 3 = 3x
x = - 1

solving for x I assume
2x-7=5x-4
add 7 to both sides,
subtract 5x from both sides
2x-7+7-5x=5x-4+7-5x
-3x=3
divide both sides by -3
x=3/-3
x=-1
