Question

resolva as equações
a) 5x+1=4x
b) 6+2x=x+4
c) 5x=10-2-2

Answer 1

a) 5x+1=4x
     5x - 4x = -1
        x = -1

b) 6+2x=x+4
     2x - x = 4 - 6
         x = -2

c) 5x=10-2-2
     5x = 6
    x = 6/5
    

Answer 2

a) 5x+1=4x
     5x - 4x = -1
        x = -1

b) 6+2x=x+4
     2x - x = 4 - 6
         x = -2

c) 5x=10-2-2
     5x = 6
    x = 6/5
