5×+8=-12
3(x-4) =-8
-3(5+×)=-3
-7(2×-6)=-146​

Answer 1

5x + 8= - 12

5x= - 12 - 8

5x= - 20

x= - 20/5

x= - 4

________________

3(x - 4)= - 8

3x - 12= - 8

3x= - 8 + 12

3x= 4

x= 4/3

________________

- 3(5 + x)= - 3

- 15 - 3x= - 3

- 3x= - 3 + 15

- 3x= 12>> .(-1)

3x= - 12

x= - 12/3

x= - 4

________________

- 7(2x - 6)= - 146

- 14x + 42= - 146

- 14x= - 146 - 42

- 14x= - 188>> .(-1)

14x= 188

x= 188/14

Answer 2

5x + 8 = -12

5x = -12 - 8 = -20

x = -20/5 = -4

3*(x - 4) = -8

3x - 12 = -8

3x = 12 - 8 = 4

x = 4/3

-3*(5 + x) = -3

5 + x = 1

x = -4

-7*(2x - 6) = -146

-14x + 42 = -146

14x = 42 + 146 = 188

x = 188/14 = 94/7
