Question

Simplifique as expressões algébricas
a) -5(3 - x)
b) 6(x + 4) + 2( x - 3
c) 5 ( x - 2) + 3(4 + x)
d) 4(x - 3) - 2(3 - x)
e) 7 (x + 2) + 5(x - 3) - 3(x - 1)
F) - ( x + 1) + 3(2x + 3) - 2(x - 4)

Answer 1

A) -5(3-X)= -15+5X

B) 6(x + 4) + 2( x - 3)= 6X+24+2X-6

=8X+18

C) 5 ( x - 2) + 3(4 + x)= 5X-10+12+3X

=8X+2

d) 4(x - 3) - 2(3 - x)= 4X-12-6+2X

= 6X-18

e) 7 (x + 2) + 5(x - 3) - 3(x - 1)= 7X +14+5X-15-3X+3

= 12X-3X +14+3

= 9X+17

F) - ( x + 1) + 3(2x + 3) - 2(x - 4)= -x-1+6x+9-2x+8

= -x+6x-2x+9+8

=3x+17
