how to solve please?
Solution:
2x - 4 = 5x + 3
2x - 4 - 2x - 3 = 5x + 3 - 2x - 3
0 - 7 = 3x + 0
-7 = 3x
-7/3 = x
subtract 2x from both sides gives
-4 = 5x + 3 - 2x
<=> -4 = 5x - 2x + 3
<=> -4 = 3x + 3
subtract 3 from both sides gives
-4 -3 = 3x
<=> -7 = 3x
<=> 3x= -7
First group what is similar.
-4-3=5x-2x
-7=3x
-7/3=x
2x – 4 = 5x + 3
-2x -2x
-4=3x+3
-3 -3
2x - 5x = 3+4
-3x = 7
x = -7/3
2x-4=5x+3
you have to group the common
so subtract three from each side
2x-4-3=5x
then subrtact 2x from each side
negative four minus three equals negative seven
-7=5x-2x
5x minus 2x equals 3x
so divide each side by 3 to get x by it self
-7/3=3x/3
so
-2.33333333=x
or leave it as a fraction
Move x's to one side, numbers to the other:
2x - 5x = 3 + 4
or, -3x = 7
or, x = -7/3 = -2.3333
This is the answer!
collect terms on each side, you get:
5x - 2x = -4 - 3
3x = -7
the answer is 3x+7

Solution:
2x - 4 = 5x + 3
2x - 4 - 2x - 3 = 5x + 3 - 2x - 3
0 - 7 = 3x + 0
-7 = 3x
-7/3 = x
subtract 2x from both sides gives
-4 = 5x + 3 - 2x
<=> -4 = 5x - 2x + 3
<=> -4 = 3x + 3
subtract 3 from both sides gives
-4 -3 = 3x
<=> -7 = 3x
<=> 3x= -7
