230=-z+148 solve for z?

solve for z

230= -z+148

Answers:
if the z is a negitive ( - ) next :

230 = -z + 148

subtract 148 from respectively side

82 = - z --> From this step:

Multiply respectively side by ( - 1) (negitive 1)

- 82 = z or z = - 82

Hope this help!!
a. this is not diet and fitness.
b. this is rough algebra.. please relate me your joking
c. except.. the answer is 82. 82+148= 230
The answer is -82.

If -82 is substituted for the unstable z, the equation become 230= -(-82) + 148. The two unenthusiastic signs negate eachother and the 82 become a positive.
z =148 - 230
