It's 9z-7. because: you do the 8 times z first (8z) then add the z, (9z), then minus 7. 9z-7

Yes, -8 plus plus 3 equals -5. The "plus plus" is equivalent to a positive sign, so -8 plus (+3) equals -5.
2 + 14z = -8 + 9zSubtract 9z from each side:2 + 5z = -8Subtract 2 from each side:5z = -10Divide each side by 5:z = -2
It's 9z-7. because: you do the 8 times z first (8z) then add the z, (9z), then minus 7. 9z-7
It is the property that equals plus equals are equals.
Without an equality sign and not knowing the plus or minus value of 81 it can't be solved. If you mean: z+81 = 9z-7 Then: z-9z = -7-81 => -8z = -88 By dividing both sides by -8: z = 11
it is 28
