Solve it as
=7x+2-3x+5
=7x-3x+2+5
=4x+7

Add the terms with x together, so 7x-3x is 4x and then add the other terms, 2+5 = 7 so you get 4x+7

7x + 2 - 3x + 5
= 4x + 7
7x + 2 - 3x + 5 = x(7 - 3) + 2 + 5

4x + 7, 7x-3x = 4x and 2+5 = 7

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

to simply this equation you need to add all the x values and then the numbers.
So 7x-3x= 4x
2+5=7
Therefore 7x+2-3x+5 simplified is 4x+7

Are you sure you wrote this down correctly? The answer is 4x+7, however if I were setting the question it would read (7x+2)-(3x_5) 'cos it's harder, the answer to that is 4x-3

You have to collect the like-terms first.
7x and -3x both have x right? so you can group them together.
+2 and +5 both are natural numbers without any sign, so group it.
Then rearrange it; like-terms together!
7x-3x+2+5
4x+7

7x+2-3x+5
can be rearanged to form
(7x-3x)+(2+5)
Which after adding or subtracting in each bracket becomes
4x+7
i hope that this explains it clearly enough
