Question

Solve the equation, justify each step with an algebraic property. -11 = -12+ 2x +3

Answer 1

`x = -1`

Explanation:

Given the equation
`-11 = -12 + 2x + 3` find
`x`

For resolve this you have to do basic algebraic operations in both sides of the equation, as follow:

First substract -3 in both sides of the equation

`-14 = -12 + 2x`

Later sum 12 in both sides of the equation

`-2 = 2x`

The final step is multiply by
`(1)/(2)` each side of the equation

`-1 = x`

So the final answer is
`x = -1`

Answer 2

-1

Explanation:

Given the equation :

-11 = - 12 + 2x + 3

Collect like terms

-11 + 12 - 3 = 2x

-2 = 2x

-2 /2 = 2x/2

x = - 1
