Hey!
-----------------------------
Question 16:
6 - x = 10
6 + (-x) = 10
6 + (-x) -6 = 10 - 6
-x = 4
-x/-1 = 4/-1
<u>x = -4</u>
Question 17:
4x + 3 = 9
4x + 3 - 3 = 9 - 3
4x = 6
4x/4 = 6/4
<u>x = 1 1/2</u>
Hope this helped, good luck!
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
