z=2v+32 z+v=176 2v+32+v=176 3v=144 v=48 z=96+32 z=128

其他解答:

first,solve z divided by v is equal to 2...32 The equation is z/v = 2...32, therefore solve this equation is z = 2v + 32 -(a) Put equation (a) into the the another equation i.e. z + v = 176 ( 2v + 32 ) + v = 176 3v + 32 = 176 3v =176 - 32 3v = 144 v = 48 Put v = 48, into equation (a) i.e. z = 2 ( 48 ) + 32 z =128 ( Answer ) The value of z is 128.
