Question

resolva da seguintes equações:

A)- 5×+5=10-3×

B)- -2×+4=-6+2×

C)- 2+5×=-4+2×

D)- 4×-10=-2×+6

E)- -2×+5=7-6×​

Answer 1

A)

- 5x + 5= 10 - 3x

- 5x + 3x= 10 - 5

- 2x = 5

x= 5/ -2

B)

- 2x + 4= - 6 + 2x

- 2x - 2x= - 6 - 4

- 4x= - 10

x= -10/ -4

C)

- 2 + 5x= - 4 + 2x

5x - 2x= - 4 + 2

3x= - 2

x= -2/ 3

D)

- 4x - 10= - 2x + 6

- 4x + 2x= 6 + 10

- 2x= 16

x= 16/ -2

x= -8

E)

- 2x + 5= 7 - 6x

- 2x + 6x= 7 - 5

4x= 2

x= 2/ 4
