Question

Equação 1 grau

1) 4 ( x – 3 ) = 2 ( x + 4 )=
2) 3 ( 2x – 4 ) = 2 ( 2x + 4 )=

3) 2 ( 3x – 2 ) = x + 16
4) 5x + 8 = 3 ( x + 4 )​

Answer 1

Resposta:

1) x=10

2) x=10

3) x=4

4) x=2

Explicação passo-a-passo:

1)

4 ( x – 3 ) = 2 ( x + 4 )

4x-12=2x+8

4x-2x=8+12

2x=20

x= $\frac{20}{2}$

x=10

2)

3 ( 2x – 4 ) = 2 ( 2x + 4 )

6x-12=4x+8

6x-4x=8+12

2x=20

x= $\frac{20}{2}$

x=10

3)

2 ( 3x – 2 ) = x + 16

6x-4=x+16

6x-x=16+4

5x=20

x=$\frac{20}{5}$

x=4

4)

5x + 8 = 3 ( x + 4 )​

5x+8=3x+12

5x-3x=12-8

2x=4

x=$\frac{4}{2}$

x=2
