Question

Simplifique às expressões algébricas:
A=4(x-1)+3(x+1)
B=-2(2x-4)+5(-2x-10)
C=2/5(x-0,2)-1/2(3x-4/25)

Answer 1

A) 4x-4+3x+3
7x-1

B) 4x-8-10x-50
-6x-58

C) $\frac{2x}{5} - \frac{4}{50} - \frac{3x}{2} + \frac{4}{50}$
$\frac{4x-15x}{10}$
$\frac{-11x}{10}$

Answer 2

A=4x-4+3x+1
A=7x-3
B=4x-8-10x-50
B=-6x-60 .(-1)
B=6x+60
C=2/5x-2/25-3/2x+2/25
