[tex]3x + 5x - 3x = 5x[/tex]
b)
[tex]z + z + z - z - z = z[/tex]
c)
[tex] - a + a + a - a = 0[/tex]
d)

e)
[tex]3xy + 4x - 5xy + 10 - 2x + 2xy = 2x + 10[/tex]
f)
[tex]3m + 2m + m - m - 2m - 4m = - m[/tex]
g)
[tex]x + 2x + 3x + 4x + 5x + 6x = 21x[/tex]
h)
[tex]4y - 2y + 3y - 8y + 2y - 4y = - 5y[/tex]
i)
[tex] {a}^{2} - 4 {a}^{2} + 3 {a}^{2} - 2 {a}^{2} + 4 {a}^{2} - {a}^{2} = {a}^{2} [/tex]
Myślę że pomogłem ;)
