Question

vocês podem resolver pra mim? ; )

Answer 1

A) 11x=64+13

11x=77
x=77 : 11
x=7

Answer 2

A) 11x - 13 = 64
11x = 77
X = 7

B) 17x + 50 = 7x
10x = -50
X = -5

C) 13x -9x + 16-12 = 0
4x + 4 = 0
4x = -4
X = -1

D) 12x + 21 = 10x + 16
12x-10x = 16-21
2x = -5
X = -5/2

E) 5.(x+2) - 2.(3x-1) = 13
5x + 10 -6x + 2 -13=0
-x = 11-10
X = - 1

F) 3.(x+1) -2.(x-1) = x+5
3x +3 -2x + 2 = x+ 5
X + 5 = x + 5
X - x = 5-5
0=0


Valeu!
