Question

If 2x + 5 = 1 then x =

-2
-1.5
0
2
none of these

Answer 1

x=-2

Explanation:

2x + 5 = 1

Subtract 5 from each side

2x + 5-5 = 1-5

2x = -4

Divide each side by 2

2x/2 = -4/2

x = -2

Answer 2

x=-2

Explanation:

To solve the given equation, we need to isolate x.

2x+5=1

We can first subtract 4 from both sides.

2x=1-5

2x=-4

Divide both sides by 2.

x=-2
