Answer:
-2
Step-by-step explanation:
1.Subtract 3 from both sides and the equation is -2z=6
2.Divide both sides by -2 and the equation is z=-3
3.Multiply -3 by 2/3 and you get -2
Answer:
2/3z = -2
Step-by-step explanation:
1. First you want to find out what z is, so you have to solve for z.
2. To solve for z, first subtract 3 from the 3 and the 9. 3 minus 3 is equal to 0, so it cancels out. 9 minus 3 is equal to 6.
3. The new equation is -2z = 6, so now you have to divide -2z by -2 and 6 by -2. -2z divided by -2 is equal to 1z or z, and 6 divided by -2 is equal to -3.
4. The simplified equation is z = -3.
5. Now that we solved for 1z, we have to solve for 1/3 by dividing 1 by 3 and -3 by 3. 1 divided by 3 is 1/3, and -3 divided by 3 is -1.
6. We have solved for 1/3z (1/3z = -1), but now we want to solve for 2/3z so we have to multiply 1/3z by 2, and -1 by 2. 1/3z times 2 is 2/3z, and -1 times 2 is equal to -2.
7. The simplified equation for the value of 2/3z in the equation -2z + 3 = 9 is 2/3z = -2
