Solve the algebraic equation: 2x + 4 = - 16

Answer:x = - 10

Step-by-step explanation

first add 4 to both sides of the equation which will cancel out the 4 and leave you with 2x = - 20

then divide both sides by 2 to get the x by itself and divide - 20 by 2 which will give you x = - 10

-10

Step-by-step explanation:

subtract 4 from both sides

divide by 2
