Answer:

4x = −4



Question 2

2(2x − 5 − 4) = 160 − 17

4x-10-8 = 160-17

4x-18=143

4x = 161

x=40.25



Question 3

4(2z + 3) = 12

8z +12 = 12

8z = 0

z = 0


Question 4


5(2x − 6) + 20 = 10

10x-30+20=10

10x-10=10

10x =20

x=2



Question 5


5x + 10 = 5x − 8

5x+18=5x

18=0

Zero solutions
