Question

Answer this question ​

Answer 1

Step-by-step explanation:

2(-1)+2 =0

-2+2=0

0=0. (x = - 1) is solving this equation.

- 1/3+3 = - 1

- 1 = - 1. ( x = - 1) is solving this equation.

3(- 1) + 1= - 2

-3+1 = - 2

- 2= - 2 (x= - 1) is solving this equation.

Answer 2

Answer:

Hey mate

Here is your solution

Step-by-step explanation:

3.(a)

2x+2=0

2*(-1)+2=0

-2+2=0

0=0

L.H.S=R.H.S

3.(b)

X/3 + 3 = - 1 (we have to take LCM of bold digits)

-1/3+3/1= - 1

-1/3+9/3= - 1

8/3= - 1

L.H.S is not = R.H.S

3.(c)

3x+1= - 2

3*(-1) + 1 = - 2

-3+1= - 2

- 2= - 2

L.H.S=R.H.S
