Answer:

x = 2

Explanation:

7x-16=-2how do i find the solution of x

7x - 16 = -2

  • move the -16 to the right and change the sign

7x = - 2 + 16

  • solve the part on the right

7x = 14

  • divide 14 by 7 and you will have the value of x

x = 14 : 7

x = 2

-------------------------------

check

7 × 2 - 16 = -2 (remember PEMDAS)

14 - 16 = -2

-2 = -2

the answer is good

Adding 16 to the given equation we get:


7x-16+16=-2+16.

Simplifying the above result we get:


7x=14.

Dividing the above equation by 7 we get:


(7x)/(7)=(14)/(7).

Simplifying the above result we get:


x=2.

Answer:


x=2.
