Whats the answer to - 2 (x+7) = 28

x = - 21

Step-by-step explanation:

Start by dividing by - 2. Then you don't have bracket problems.

-2 (x + 7) = 28

-2/-2 (x + 7) = 28 / - 2 Do the division

x + 7 = - 14 Subtract 7 from both sides

x + 7 - 7 = - 14 - 7 The 7's on the left Cancel. Think money for - 14-7

x = - 21

x = - 21

Step-by-step explanation:

-2 (x+7) = 28

simplify the bracket with - 2

-2 * x + - 2 * 7 = 28

-2x - 14 = 28

combine the like terms

-2x = 28 + 14

whenever a negative or positive crosses an equal sign, the negative changes to positive or if it is positive, the sign changes from positive to negative.

-2x = 42

divide by - 2

x = 42

-2

x = - 21
