a)
[tex] - 2 - 2a + 3 = 2a + 1[/tex]
b)
[tex]2a - 3b + 3a - 2b = 5a - 5b[/tex]
c)
[tex]2y - 6y + 4x - 2x = - 4y + 2x[/tex]
d)
[tex]2x + 3 - 6x - 10 = - 4x - 7[/tex]
e)
[tex] - x + 2x + ( - 6) + x - 4 = 2x - 10[/tex]
f)
[tex]2ab - 6 - ab - ( - 3) = ab - 3[/tex]
g)
[tex]3 {x}^{2} - 2 {y}^{2} - 6 {x}^{2} - 2 {y}^{2} = - 3 {x}^{2} - 4 {y}^{2} [/tex]
h)
[tex]3.5b - 2.4c - 0.6c - 0.5b = 3b - 3c[/tex]
i)
[tex]3 {x}^{2} - 2x + 1 + x - 4 {x}^{2} - 2 = - {x}^{2} - x - 1[/tex]
j)
[tex]2 {m}^{2} + 3mn - n + mn + 3n - {m}^{2} = {m}^{2} + 4mn + 2n[/tex]
Odpowiedź:
Szczegółowe wyjaśnienie:
=1 -2a
=5a -5b
=2x- 4y
= -4x -7
=2x-10
=ab -3
= -3x^2-4y^2
=3b -3c
= -x^2 -x-1
=m^2+4mn+2n
