Question

20) Pick out the solution from the values given in the bracket next to each equation.
Show that the other values do not satisfy the equation
x + 7 = ‒ 2 ( 2 , ‒5 , ‒9 )

Answer 1

Answer:

-9

Step-by-step explanation:

x + 7 = -2

x = -2 -7 ( When there is a minus sign on both sides, they are added to each other and the charge between them is the largest. )

know the answer is X = - 9
