17z + 34 = 6z + 5
17z - 6z + 34 = 6z - 6z + 5
11z + 34 = 5
11z + 34 - 34 = 5 - 34
11z = -29
11z/11 = -29/11
z = -2 7/11 or -29/11
Double check your answer:
17z + 34 = 6z + 5
17(-2 7/11) + 34 = 6z + 5
-44 9/11 + 34 = 6z + 5
-10 9/11 = 6z + 5
-10 9/11 = 6(-2 7/11) + 5
-10 9/11 = -15 9/11 + 5
-10 9/11 = -10 9/11
17z + 34 = 6z + 5 when Z = -2 7/11

6z + 28 = 12z + 10 18 = 6z 3 = z
-6z + 2 = 3z + 4z + 28 Add 6z to both sides: 2 = 3z + 4z + 28 + 6z = 28 + 13z Subtract 28 from both sides: - 26 = 13z Divide both sides by 13: -2 = z
-6z + 16 = 52 subtract 16 from each side -6z = 36 divide by -6 z = -6
63 + 20 - 60 = 23
-6z 2 = 3z+ 4z+28 -6z+2 +3z = 3z+ 4z +28 +4z -6z+4z+2 = 3z+ 28 -10z+2 -3z= 28 - 2 -10z + -3z = 26 -13z/13 = 26/-13 z = -2
