Question

Help me solve for 16 and 17

Answer 1

Answers:

16. 6-x= 10

move +6 to the other side

sign changes from +6 to -6

6-6-x= 10-6

-x= 4

Mutiply both sides by -1

(-1)(-x)= (-1)(4)

x= -4

17. 4a+3= -9

move +3 to the other side

sign changes from +3 to -3

4a+3-3= -9-3

4a= -12

divide both sides by 4

4a/4= -12/4

a= -3

Answer 2

Hey!

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

Question 16:

6 - x = 10

6 + (-x) = 10

6 + (-x) -6 = 10 - 6

-x = 4

-x/-1 = 4/-1

x = -4

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

Question 17:

4x + 3 = 9

4x + 3 - 3 = 9 - 3

4x = 6

4x/4 = 6/4

x = 1 1/2

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

Hope this helped, good luck!
