Question

16) Resolva com atenção as equações abaixo:
a) 2(3x + 1) = 6+43
b)) 5x + 6x - 16 = 3x + 2x - 4
c) 2(4x+1)= 6 + 44​

Answer 1

Explicação passo-a-passo:

a) 2(3x + 1) = 6+43

2 .(3x+1)=6+43

2.(3x)+2.(1)=49

6x+2=49

6x=49-2

6x=47

x=47/6

b)) 5x + 6x - 16 = 3x + 2x - 4

5x+6x-16=5x-4

11x-16=5x-4

11x-5x=-4+16

6x=12

x=12/6

x=2

c) 2(4x+1)= 6 + 44

2.(4x+1)=50

8x+2=50

8x=50-2

8x=48

x=48/8

x=6

Espero ter ajudado!

Answer 2

A) 2(3x + 1) = 6+43

2.3x+2.1=49

6x+2=49

6x=49-2

x=47/6

b) 5x + 6x - 16 = 3x + 2x - 4

11x-16=5x-4

11x-5x=-4+16

6x=12

x=12/6

x=2

c) 2(4x+1)= 6 + 44

2.4x+2.1=50

8x+2=50

8x=50-2

x=48/8

x=6
