3Z+6Z+7=29-4 Please shoe how to solve this
Problem.
3Z+6Z+7=29-4
9Z + 7 = 25
9Z = 25 - 7
9Z = 18
Z = ?
If you post your answer, we'll be glad to check it for you.
Answer: Z2 Thank you
Z = 2
Ms Sue, Thank you very much. I hope you can help with another problem. I get mixed up on changing the plus and minus.
4a+17=a-13. I do know that the second
a is a 1.
To solve the equation 3Z + 6Z + 7 = 29 - 4, we need to simplify the expression on both sides.
First, we can combine the like terms on the left side of the equation. The like terms are those with the same variable, in this case, Z. So, adding 3Z and 6Z gives us 9Z.
Now, the equation becomes 9Z + 7 = 29 - 4.
Next, we simplify the right side of the equation. Subtracting 4 from 29 gives us 25. The equation now becomes 9Z + 7 = 25.
To isolate the variable Z, we need to get rid of the constant term of 7. We can do this by subtracting 7 from both sides of the equation.
9Z + 7 - 7 = 25 - 7
This simplifies to 9Z = 18.
Finally, to solve for Z, we divide both sides of the equation by the coefficient of Z, which is 9.
(9Z)/9 = 18/9
Canceling out the 9s on the left side, we get:
Z = 2
Thus, the solution to the equation 3Z + 6Z + 7 = 29 - 4 is Z = 2.
