Add 3 from both sides:
2x=7
Divide 2 from both sides:
x=7/2
Check:
2(7/2)-3=4
7-3=4
4=4

6-4(x-3)=2x-4(2x-3) distribute the -4, and the -4 6 - 4x + 12 = 2x - 8x + 12 subtract 12 from both sides 6 - 4x = 2x - 8x combine terms 6 - 4x = -6x add 4x to both sides 6 = -2x divide by the variable's coefficient (which is -2) -3 = x Hope this makes things clearer!

This is a very straightforward algebra problem.
If you are having trouble with this you probably need to review the common methods for solving simple equations.
They generally consist of applying the same multiplication, addition, division, or subtraction to both sides of the equation. By doing the same thing to both sides, the equation is still the same, still equal, although it is expressed differently then and can show the value of the chosen variable.
add 3 to each side
2x -3 +3 = 4 + 3
2x = 7
divide each side by 2
2x/2=7/2
x=7/2
good luck
keep at it

2x - 3 = 4
you want to find x, get all other numbers on the right hand side of the equation,
2x - 3 = 4
2x = 4 + 3
(-3 becomes +3 when its taken on the other side of the equation)
2x = 7
x = 7/2
(2 multiplied by 'x' will become denominator when taken on the other side of the equation)
x = 3.5

2x -3 =4
u want to get the "X" by itself so u want to get rid of that -3
add 3 to both sides and it will be
2x=7
now divide :)
x = 7/2

2x-3=4
+3 +3
2x=7/2
x=3.5
THE ANSWER IS 3.5. X IS 3.5
