Question

A) 2(x-3)=3 (x-3)
B) 4 (5x-3)-64 (3-x)-3 (12x-4)=96

Answer 1

A) 2(x-3)=3 (x-3)

2x-6=3x-9

2x-3x=-9+6

-x=-3

x=3

B) 4 (5x-3)-64 (3-x)-3 (12x-4)=96

20x-12-192+64x-36x+12=96

20x+64x-36x = 96 + 12 + 192 - 12

48x = 288

x = 6

Answer 2

Olá, boa noite ☺

Resolução:

a)

2(x-3)=3 (x-3)

2x - 6 = 3x - 9

2x - 3x = - 9 + 6

-x = - 3 .(-1)

x = 3

b)

4 (5x-3)-64 (3-x)-3 (12x-4)=96

20x - 12 - 192 -+ 64x - 36x + 12 = 96

20x + 64x - 36x = 96 + 12 + 192 - 12

48x = 288

x=288/48.

x=6

Bons estudos :)
