First of all, 7(4w - 3) = 28w - 21, then
28w - 21 - 25w = 3w -21

distribute 7 to the equation (4w - 3)
7*4w - 7*3 - 25w
28w - 21 - 25w
3w - 21 ---> reduce to lowest term 3(w-7)

7(4w-3)-25
7*4w -7*3-25w
28w-21-25w
28w-25w-21
3w-21
if you want to solve for w, see the next steps
3W-21+21=0+21
3W+0=21
3W/3=21/3
w =7

Use the distribution method
(7)(4w)+(7)(-3) - 25w
28w-21-25w
3w-21 this is most simplified form

offffffffff, how cool, another kid cheating himself out of an education.
7*4w=28w
7*-3=-21
28W-21-25W ---combining like terms
3W-21

expand brackets 7*4w-7*3-25w
equals 28w-21-25w
simplify 3w-21 or factorise 3(w-7)

= 28w - 21 - 25w
= 3w - 21
= 3.(w - 7)
