Question

Resolva a equações ?
A) 4x +11-7x=-11
B) 5x-(-x+22)= -4
C) 11x-(-3x+10)=4x+2

Answer 1

A) 4x +11-7x=-11

-3x = -11 - 11

-3x = -22

x = -22/-3

x = 22/3

B) 5x-(-x+22)= -4

5x + x - 22 = -4

6x = -4 + 22

x = 18/6

x = 3

C) 11x-(-3x+10)=4x+2

11x +3x -10 = 4x + 2

14x - 4x = 2 + 10

10x = 12

x = 12/10

x = 6/5
