Question

1)Resolva às operações a seguir:

Answer 1

Resposta:

1) x-4=3

z=3+4

x=7

2) 36x=12

x=$\frac{12}{36}$ (÷12)

x=$\frac{1}{3}$

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

11x-16=5x-4

11x-5x=16-4

6x=12

x=$\frac{12}{6}$

x=2

4) 4x-10=2x+2

4x-2x=10+2

2x=12

x=$\frac{12}{2}$

x=6

5) 5x+4=3x-2x+4

5x+4=x+4

5x-x=4-4

4x=0

x=0
