well you should start with
9z + 10 = 145
then balance the equation by collecting like terms
9z = 145 - 10
solve
9z = 135
then divide both sides by the number next to the variable. (in this case 9)
so 9z/9 = 135/9
solve
z = 15

The following steps lead you to the correct answer: 9z = 5z + 16 9z - 5z = 16 4z = 16 z = 4, thus the correct answer is z = 4
12x-4y plus 9z plus 2y?
12x-4y+9z+2y =12x-2y+9z
What is the answer to -3z plus 17 plus 12z equals 11?
-3z+17+12z = 11 9z = -6 z = -2/3
2 plus 14z equals -8 plus 9z?
2 + 14z = -8 + 9zSubtract 9z from each side:2 + 5z = -8Subtract 2 from each side:5z = -10Divide each side by 5:z = -2
What is the quadratic root of z squared plus 9z plus 18 equals 0?
use the quadratic formula. when done so the roots are z=-3, and z=-6
What is 2 plus 4z plus 6 - 9z - 5?
3-5z
How do you solve 9z plus 10-6z equals 7 plus 2z-3?
9z + 10 - 6z = 7 + 2z - 3 gather together z terms on the left 3z + 10 = 7 + 2z - 3 gather integers on the right 3z + 10 = 2z + 4 subtract 2z from each side z + 10 = 4 subtract 10 from each side z = - 6 ----------------check in original equation 9(- 6) + 10 - 6(- 6) = 7 + 2(- 6) - 3 - 54 + 10 + 36 = 7 - 12 - 3 - 8 = - 8 --------------checks
How do you factor 9z plus 12?
