Question

How many solutions for x does the following equation have? 2(x + 4) − 1 = 2x + 7

Answer 1

The equation has infinity solutions

Explanation:

we have

`2(x+4)-1=2x+7`

Applying distributive property left side

`2x+8-1=2x+7`

Combine like terms

`2x+7=2x+7`

The linear equation of the left side is equal to the linear equation of the right side

Both lines are identical

therefore

Is a consistent dependent system

The equation has infinity solutions
