Answer:

x = - 7

Explanation:

From the diagram

NM + ML = NL ( substitute values )

x + 12 + 2x + 20 = 11 ( collect like terms on left side )

3x + 32 = 11 ( subtract 32 from both sides )

3x + 32 - 32 = 11 - 32 ( simplify both sides )

3x = - 21 ( divide both sides by 3 )


(3)/(3) x =
(-21)/(3) , that is

x = - 7
